The Source of Legal Obligations Flashcards
(112 cards)
Obligations:
- key question re obligation to obey the law
- Raz on law’s effect
- Dworkin on law’s effect
- Prudential reasons?
- not that there’s always an obligation to obey every law, but rather how law changes our reasons, which particular reasons, and whether these reasons count as obligations.
- Raz – laws create exclusionary reasons and legal duties are therefore these exclusionary reasons
- Dworkin (Greenburg, Hershovitz, Stavropolous): no need to discuss exclusionary reasons etc. – the law doesn’t have exclusionary effect. It gives ordinary first order reasons (albeit strong ones), so the presence of exclusionary reasons isn’t an objection to them.
What kinds of reasons does the law give us? - Prudential reasons (though this isn’t an obligation – it’s more like reasons to avoid dangerous animals etc.)
Introduction
Do we have a general obligation to obey the laws of our legal system?
- what do liberal anarchists argue?
- what if acting in conformity with the directives is the right thing to do?
- how have legal scholars responded re locating the general obligation to obey the law? (4 points)
- 2 follow up questions:
- Liberal anarchists famously argued that acceding to the claims of authority of one’s legal system—even if it is a reasonably good legal system—is fundamentally incompatible with one’s autonomy. Therefore, they suggested, one should never comply with legal directives (or the directives of any supposed authority, for that matter).
- Of course, acting in conformity with certain directives will often be the right thing to do, but that is coincidental and therefore beside the point.
- In response to the anarchist challenge, scholars have tried to locate a general obligation to obey the law in a legal system’s effectiveness in solving coordination problems, the substantive justice of its laws, its democratic decision-making procedures or the true community it fosters.
- If they fail and we are forced to agree with the anarchists that there is indeed no general obligation to obey the law,
- does that still leave open the possibility of a legitimate legal system?
- Even if it turns out that there is no general obligation to obey the law, is there nonetheless a right way to relate to the laws of a legitimate legal system?
R. Wolff, In Defense of Anarchism (1970) ch 1: “The Conflict between Authority and Autonomy
I - The concept of authority
- definition of a state and its distinctive characteristic?
- definition of authority?
- First question: under what conditions and for what reasons does one man have supreme authority over another?
- The state is a group of persons who exercise supreme authority within a given territory, and may include all the persons who fall under its authority. Its distinctive characteristic is supreme authority – sovereignty
- Authority is the right to command and correlatively the right to be obeyed, distinguished from power: the ability to compel compliance.
- We must demonstrate by an a priori argument that there can be forms of human community in which some men have a moral right to rule. Legitimate (de jure) authority thus concerns the grounds and sources of moral obligations; de facto states are simply states whose subjects believe it to be legitimate – although they may be wrong. Since some people do so believe, there are de facto states.
R. Wolff, In Defense of Anarchism (1970) ch 1: “The Conflict between Authority and Autonomy
II - The concept of autonomy
- what is the fundamental assumption in moral philosophy? where does the obligation NOT derive from?
- what does a responsible individual acknowledge?
- how might we say a man is autonomous
- how might we say he is free?
- can man abdicate his autonomy?
- can man give up responsibility for his actions?
- The fundamental assumption of moral philosophy is that men are responsible for their actions; this obligation does not derive from man’s freedom of will alone, for more is required in taking responsibility than freedom of choice.
- A responsible individual does not imply that he always does what is right but only that he does not neglect the duty of attempting to ascertain what is right. He does acknowledge himself bound by moral constraints, but he insists that he alone is the judge of those constraints.
- Since the responsible man arrives at moral decisions which he expresses to himself in the form of imperatives, we may say that he gives laws to himself or is self legislating – autonomous.
4, He may do what another tells him but not because he has been told to do it – he is therefore, in the political sense of the word, free.
- Since man’s responsibility for his actions is a consequence of his capacity for choice, he cannot give it up or put it aside, but he can refuse to acknowledge it – therefore, man can forfeit his autonomy at will: he can decide to obey the commands of another without making any attempt to determine for himself whether what is commanded is good or wise. We frequently forfeit our autonomy – by giving to the force of tradition or bureaucracy.
- This is not the same as the false assertion that a man can give up responsibility for his actions - the moral condition demands that we acknowledge responsibility and achieve autonomy wherever and whenever possible.
R. Wolff, In Defense of Anarchism (1970) ch 1: “The Conflict between Authority and Autonomy
III - The conflict between authority and autonomy
- what is the defining mark of the state?
- what is the primary obligation of man?
- why is anarchism consistent with autonomy?
- does the feeling of a special obligation to the law have an objective basis?
- is all authority equally wrothless according to the anarchist?
- why is a de jure legitimate state vacuous?
- The defining mark of the state is authority, the right to rule.
- The primary obligation of man is autonomy, the refusal to be ruled. Insofar as a man fulfills his obligation to make himself the author of his decisions we will resist the state’s claim to have authority over him; he will deny that he has a duty to obey the laws of the state simply because they are laws.
- Thus, anarchism is the only political doctrine consistent with the virtue of autonomy. An anarchist may grant the necessity of complying with the law under certain circumstances or for the time being, but he will never view the commands of the state as legitimate, as having a binding moral force.
- The anarchist tells me my feeling of a special obligation to obey its laws is purely sentimental and has no objective moral basis.
- All authority is equally illegitimate, although of course not therefore equally worth or unworthy of support
- . If all men have a continuing obligation to achieve the highest degree of autonomy possible, then there would appear to be no state whose subjects have amoral obligation to obey its commands. Hence the concept of a de jure legitimate state would appear to be vacuous, and philosophical anarchism would seem to be the only reasonable political belief for an enlightened man.
Bix, Jurisprudence: Theory and Context
Intro
- what is the seminal q?
- what do most writers assume?
- reasons for obeying the law?
- what is the focus of the debate?
- what are the various theories?
- what are the various scenarios?
- The question is whether there is a moral obligation to obey the law, a moral obligation that attaches to a rule simply because of its legal validity, i.e. its membership within a legal system.
- Most writers assume:
1) A generally just legal system
2) There is a prima facie obligation that can be overridden if a stronger moral obligation requires a contrary action - Reasons for obeying the law:
1) Prudential reasons (fear of imprisonment or fine)
2) Habit (easier to obey the law unreflectively rather than calculating the moral and prudential factors on each occasion) - These reasons aren’t the focus of the debate – the question is whether the legal status of a command, by itself, without more, adds any moral reasons for doing/not doing an action.
- Various theories:
1) Consent
2) Gratitude
3) Reciprocity
4) Consequences - In all cases, the difficult scenario is one where there is seemingly no risk of harming anyone, and the disobedience seems like it would go undetected (ex. stop sign at 3AM).
Bix, Jurisprudence: Theory and Context
I – Consent
- thesis?
- steps to the argument?
(i) step + possible response?
(ii) step 2 + response? - what is the real question?
- what is a possible response?
- Thesis: by some action (voting, accepting government benefits, not leaving the country) or inaction, we have implicitly consented to obeying society’s law.
- Steps to this argument:
(i) A certain action constitutes “consent” to obeying the society’s laws – response is that these activities cannot be properly understood as consent, because a) citizens do not perceive of their action that way, and b) do not have reasonable alternatives.
(ii) Consent in this way leads to a moral obligation to obey the law - even if these activities can constitute the consent, consent doesn’t necessarily equate an obligation to obey the society’s laws. Why?
a. Acts of consent may have limited force: a mere promise is not sufficient to maintain large moral claims, like creating a moral obligation to do something a) on one-sided terms (paint your house for $1), b) immoral (kill your father), c) give up one’s autonomy (do anything you told me to for a month). In the same way, mere consent may not be sufficient to justify creating a broad obligation to obey whatever the government might enact from that day onward.
- The real question: how do we create moral obligations for ourselves, and what are the limits of these obligations? The extent to which consent can create, waive or defeat legal and moral obligations is a difficult theoretical question – thus, consent offers at best, a partial response.
- Possible response: consent only creates an obligation to obey a generally just regime, not just any regime – but even if this is true, is it consent, or the justice of the regime itself, that creates the obligation to obey, consent merely working to limit certain types of legitimate complaint by the citizen?
Bix, Jurisprudence: Theory and Context
II – Consequentialist approach (Hobbes, Honoré)
- thesis
- Hobbes?
- Honore
(i) response?
(ii) counter-argument to the response
- Thesis: the obligation arises from the bad consequences to society if people did not have such an obligation.
- Hobbes (extreme version): the law is to be obeyed even when it is unjust, because the alternative is the chaos of the state of nature, the law of all against all (Hobbes, Leviathan: “though of so unlimited a [Sovereign] Power, men may fancy many evil consequences, yet the consequences of the want of it, which is the perpetual war of every man against his neighbour; are much worse”)
- Honoré: if the initial presumption is that the law need not be obeyed, then people will tend more often to disregard the law than if the initial presumption is for obedience, leading to an “attitude of disobedience” and the breakdown of the order and cooperation needed for society to function
(i) Response: fear of legal sanctions and pre-existing moral commitments are enough to prevent the consequences of disobedience
- though not really - notwithstanding the fact that many crimes do go unaddressed, great psychological comfort comes from the fact that we are all abiding by the same (overarching) rules. Even though in a city like London, cultural norms differ, the knowledge that there is a common denominator in these norms fosters solidarity, an essential evolutionary requirement as a remarkably social creature. The challenge, as seen with the EU project, is in finding the balance.
Further, taken to its extreme, such ‘solidarity’ creates rigid borders and can drown out other values i.e. differing views. But in a moderated form, it provides enough structure to demarcate the boundaries of our rules, whilst leaving scope for debate and development. Such a vision of the law can be supported by reference to an experiment in a children’s playground. Clearly defined boundaries led to the children wandering to the very edge of those boundaries. However, the absence of any boundaries meant that the majority stayed much closer to the central building.
Bix, Jurisprudence: Theory and Context
III – Benefit or gratitude (Plato)
- thesis?
- analogy to…? - responses?
- 4 points
- Thesis: it is immoral for those who have received substantial benefits from the state not to respond with the same obligation that governments ask in return – obedience to the law (by analogy to the duty of children to their parents).
- Responses:
- children don’t owe parents the obligation to let them determine all our future choices – so is gratitude to government sufficient to give it moral authority over our actions?
- we can only owe a moral obligation if we voluntarily accept such benefits and intend to continue to do so, whereas most people don’t have the power to waive their rights to receive them
- further, many would prefer limited interference by the state!
- On the other hand, the law does coordinate activities and that given that we inadvertently take advantage of the effects of this coordination i.e. we can safely drive to work knowing which side of the road to drive on, the abide so others can carry out their
The law is therefore a traffic light, finding workable combinations to give as much liberty (given that our prevailing moral political philosophy stems from Mill) to all citizens.
Bix, Jurisprudence: Theory and Context
IV – A duty to support and to further just institutions (Rawls)
- thesis
- response?
- Thesis: the natural law position that if laws are just, they have the power of binding in conscience, a power which comes from the Eternal Law from which they are derived (Aquinas).
- Responses: even if this is true, it doesn’t create a general moral obligation to obey every law on every occasion, as many instances of disobedience simply do not undermine just institutions.
Bix, Jurisprudence: Theory and Context
V – Fairness or reciprocity (Hart)
Thesis: obedience is not a duty to the state but a duty to one’s fellow citizens – “when a number of persons conduct any joint enterprise according to rules and thus restrict their liberty those who have submitted to their restrictions when required have a right to a similar submission from those who have benefitted by their submission” (Hart, Are There Any Natural Rights?). Someone who disobeys the law is unfairly taking advantage of other people’s sacrifices.
Bix, Jurisprudence: Theory and Context
VI – There is no moral obligation to obey the law (Fuller)
- what does Fuller argue?
- what does Raz argue?
- what is an objection to Raz’s view?
- what do sceptics argue re obligation to obey the law?
- questions to distinguish?
- what does Smith argue?
- In the course of the Hart-Fuller debate Fuller argues that if, according to legal positivism, the validity of a law is separate from its moral value, then how can the legal positivists speak of a “moral dilemma” about whether to obey a morally dubious law? (Fuller, Positivism and Fidelity to Law). Just because something is required by law, it is not by itself a moral reason for doing that action.
- But some legal positivists accept that the legal status of a norm may give it no intrinsic moral weight (Raz) – they don’t argue that we should never obey the law, but only that the moral reasons must go beyond the simple “because the law says so”.
- Raz: we have a moral obligation to obey the law if and when we believe that we are more likely to make the morally best choice by following the law than by making our own judgment (because the legislator heard expert testimony, because of coordination problems). But the most common situation is that what the law requires is when the action is the moral thing to do, regardless of what the law says. - [Objection: how can you know that you have a better idea of what is morally right than the legislature?]
- Sceptics say that the arguments for a general moral obligation to obey the law is insufficient to ground a general obligation – if disobeying a law causes no harm and doesn’t create a bad example, how is it going to undermine a just institution or a joint enterprise? Why should consent or a duty of fair play/gratitude extend to all laws – even where disobedience is harmless. Why should we continue to have the obligation to obey a coordinating law if it has become clear that it failed at coordinating?
- Questions to distinguish:
1) ethical question: what should I do in this situation?
2) meta-ethical question: what is the set of beliefs and attitudes we want or need the public to hold?
3) political question: from perspective x, what is the set of beliefs and attitudes we want or need the public to hold? (not covered here) - Smith: even if there is a moral obligation, it carries little moral weight because:
1) a seriously immoral act does not become significantly more or less culpable depending on whether the action is legally permitted or not
2) we are slow to condemn someone for breaking the law until we find out which law was broken

VII – Connections
This topic is connected to more basic questions of:
Difference in adopting natural law vs positivist view
This topic is connected to more basic questions of:
1) Moral theory (what grounds our moral duties: benefit? consent? cooperation? consequences? necessity? interdependence?)
2) Legal theory (how do we determine the existence or validity of a law or legal system?)
If you start with traditional natural law theory, then your conclusion about whether something is “law” will incorporate much of the answer about whether one has an obligation to obey the law (ex. you have an obligation to obey just laws, and a minimal obligation to obey unjust laws for public compliance so as not to undermine a generally just legal system).
But if you’re a legal positivist, then because the validity of law is independent from its merits, then you need to find your answers elsewhere.
Penner, Textbook on Jurisprudence
I – A necessary prima facie moral obligation to obey the law
It was assumed that for the State and the law to function, it was necessary that subjects of the law had a prima facie (i.e. defeasible) obligation to obey the law – so the debate is how the obligation should be explained. This is the starting point of:
Penner, Textbook on Jurisprudence
A - Plato/Socrates (Classical Greco-Roman natural law)
Plato, in The Last Days of Socrates, purports to present statements of Socrates in relation to law and the duty of obedience:
- Apology: the State has no right to demand that a person commit evil or injustice – where this is in fact demanded, the only honorable course is refusal.
- Crito: addresses the different question of where the state (through its law) doesn’t command wrong of an individual but does wrong to him.
o Three grounds of obligation to comply with the law, of which an analogy with the relationship of parent and child and State and citizen: the obligation arises from gratitude for the law maintaining a system in which the individual has chosen to reside (assumes that individuals are free to depart). By disobeying, an individual attempts to destroy the law and the social fabric that it supports and which that individual must be taken to have accepted by remaining in the state.
o So if you don’t approve you have three options: move, persuade the state to amend the law, or obey. This assumes that 1) persuasion is possible and 2) legitimate departure is possible. But in practice this may not be true (ex. potential victims of genocide in the Third Reich can neither persuade nor depart – should they then submit willingly to slaughter?)
Inconsistency between the argument for disobedience in Apology and obedience in Crito, possibly explained by a distinction between a duty to do no wrong to others, and a duty to accept an unjust infliction pursuant to an obligation already accepted. So while Plato denies the right of the State to command evildoing, it denies simultaneously the right of an individual to refuse submission when wrongful acts are commanded by the law to be done to him (subject to persuasion and prior departure).
Penner, Textbook on Jurisprudence
B - Finnis (Natural Law Revival)
4 types of obligations
dismissal of these into separate disciplines
division between moral and collateral moral
Four types of obligations: 1) sanction-based (Bentham), 2) intra-systemic formal (Austin), 3) moral (Hart) and 4) collateral moral (natural law theories).
The dismissal of some of these into other disciplines is unsound jurisprudential method. The idea of “obligation” is not a singular phenomenon but a combination of different obligatory factors (coercive, formal and moral).
The division between moral and collateral moral is that by disobeying a law (even a bad one) a person places at risk the whole legal system and there is therefore a “collateral” moral obligation to obey such a law notwithstanding its immorality.
Penner, Textbook on Jurisprudence
C – Theories justifying a general moral obligation
1 – Consent
- problem
- response
- Problem = absence of actual consent.
- Response = notional consent (i.e actual consent is unnecessary where consenting would be a reasonable thing to do), but this dispenses with consent altogether rather than depending upon it, because if it would not be reasonable to consent, then actual consent can’t justify it, and if it is reasonable, actual consent is unnecessary.
Penner, Textbook on Jurisprudence
C – Theories justifying a general moral obligation
2 – Fair play/benefit and burden
- what is it?
- does it justify an obligation to a general system of law?
- Between state and citizen
- Between citizens (insisting on one’s own legal rights entails respecting the legal rights of others)
But the obligation we’re trying to justify is a general moral obligation to obey every law of the system just because it is a law of the system – fair play is a moral obligation of its own, and complying with it doesn’t justify complying with every rule that forms part of whatever body of laws is laid down by an authority (indeed some laws even contribute to unfairness: tax regimes).
Penner, Textbook on Jurisprudence
C – Theories justifying a general moral obligation
3 – Violation sets an example to others (Finnis)
2 counter-arguments
It encourages disobedience causing harm to the legal system, making it less effective. This is hopeless:
1) Certain instances of disobedience may shock people and encourage greater obedience
2) Many acts of disobedience would never be detected
Penner, Textbook on Jurisprudence
D – Denying a general moral obligation
RAZ
- people who respect their communities
- is this sufficient to ground a general obligation to obey the law?
- what paradox does Raz highlight?
- what 2 categories of law does Raz distinguish?
- what are the different rationales for obeying each?
- Raz: certain people, i.e. those who respect and are more or less deeply committted to their communities, may come under a general obligation to obey the law as an expression of that respect, but that does not ground a general obligation for everyone (by analogy with friendship creating certain special, expressive reasons to act in certain ways)
o Paradox: how can a good state with a right to rule have that right if its subjects don’t have a general duty to comply with its directives?
o Raz’s response: distinguishes
♣ laws that address wrongs mala in se (morally wrong in themselves) – here one has a moral obligation not to do the wrong (ex. murder, steal) whether the laws says so or not. Where there are prudential reasons, then these are additional reasons but not moral ones.
♣ laws that address wrongs mala prohibita (depend for their wrongfulness on the fact that they have been made the subject of regulation) – the latter case serves coordination purposes, and for Raz, the fact that there is a law doesn’t create the obligation, it’s that the law works so that people do indeed coordinate their behaviour that creates the obligation (ex. you have an obligation not to pollute the river if everyone else refrains from polluting the river, but you wouldn’t if others were polluting the river, whether a law says you can’t or not). It’s the fact of social coordination itself that gives the moral reasons to join it.

NOTE: according to HT, Green treats Dworkin’s associative obligations theory unfairly and briefly.
Political obligation: the moral obligation to obey the law. Voluntarists think that this requires a voluntary subjection to law’s rule (eg. consent), while non-voluntarists think that the value of a just and effective legal system is in itself sufficient to validate law’s claims.
Legal obligation: legal requirements with which the law’s subjects are bound to perform that the law renders non-optional. It is different from compulsion, in that subjects can choose to break the law, but it is also different from a weighty reason to conform, because such is neither a sufficient (SC has no obligation not to reverse itself too often but it still has important reasons not to) nor necessary (there is an obligation not to tread on another’s lawn, but this is only a trivial reason) condition.
- NOTE: But are these really two examples of the condition being unnecessary rather than the first being insufficient? The first simply shows that the law is not the only weighty reason to act a certain way – the only difference between the two examples is that there is an obligation to do one and not the other, though this obligation doesn’t seem to play much of a role.
Command: According to Austin, command = an expression of will + an attached risk, however small, of suffering an evil for non-compliance. It accounts for the stringency of obligations: “When I am talking directly of the chance of incurring the evil … I employ the term duty, or … obligation”.
Political authority is a right to rule with a correlative duty to obey. Legal authority is a subcategory, but it is contrasted with theoretical authority, the authority held by experts, which doesn’t claim a right to obedience or even to be believed.
Law: to engage in a debate about whether there is an obligation to obey the law, we will describe the nature of law as 1) institutionalized (connected to courts, legislatures etc.), 2) of wide scope (governing a large, loosely structured and open-ended group) and 3) morally fallible. It is after adopting this definition that political obligation turns on the moral reasons to obey mandatory requirements of a wide-ranging, morally fallible, institutionalized authority.
Non-voluntarist theory: A theory is non-voluntarist if its principles justifying legal authority do not invoke the choice or will of the subjects among its reasons for thinking they are bound to obey.
Constitutive obligations: A non-voluntarist theory that argues against looking for moral justifications for a duty to obey because a political association, like membership in any group, is itself pregnant with obligations (Dworkin)
Instrumental justification: A non-voluntarist theory where law can be instrumentally justified because it helps subjects comply better with reasons that are relevant to them. Raz’s normal justification theory is an example.
Necessity: The law is justified when it helps people comply with reasons but only if it is restricted to the domain of necessary social functions. Philosophers disagree as to what is necessary: Klosko confines it to “presumptively beneficial public goods”, while Finnis allows self-evident values including life, knowledge, play and religion. Rawls would also allow just arrangements not yet established.
Voluntarist theory: Political authority depends on the voluntary subjection to law’s rule.
Consent: Political authority requires the consent of its subjects. Locke is a proponent, defining consent as including enjoyment of benefits of government.
Expressive obligations: we are bound to obey the law because it is an appropriate expression of gratitude, respect and sense of belonging to the community. Raz thinks that the same reason we owe obligations to our friends justifies obligations to the law.
Fairness: the most influential voluntarist argument, propounded by Hart and Raz: political obligation grounds in a willingness to benefit from a system of mutual restraint. If we benefit from others not breaking the law, we owe an obligation not to break it ourselves.
Notes
I. OBLIGATIONS IN THE LAW
i. How should the law be presented?
- Bentham (Kelsen)?
- Hart and Raz? (and where do they differ?)
- Honore and Dworkin?
- Bentham: “Every article of law has in common with the rest [in that it] commands and by doing so creates… obligations.” Therefore, Bentham and Kelsen think that the content of a legal system should be presented solely in terms of duty-imposing and duty-excepting laws, because it reveals the conditions under which the coercive power of law will be met
- Hart and Raz think that this presentation would be uninformative and unwieldy, but while Hart is concerned about it concealing the social functions of law, Raz thinks that it hides the different kinds of reasons for action that they create
- Honoré and Dworkin both devised theories that bypassed the issue [Does this show that it is meaningless, unimportant
Notes
I. OBLIGATIONS IN THE LAW
ii. What accounts for the stringency of legal obligations?
Content:
- Green?
- Green thinks that the content of legal obligations does not account for their stringency, because it is neither sufficient (high courts have no obligation not to reverse themselves too often but they still have important reasons not to) nor necessary (we have an obligation not to trample on other people’s lawns, but this is only a small reason) for someone to pursue a certain course of action.
[I think this doesn’t show that it is insufficient, only unnecessary – the first example only shows that there are other very weighty reasons and that a legal obligation is therefore unnecessary. Also, the law is usually couched in absolute terms: a law not to do something too often is simply unenforceable. The difference between law and other reasons is that the law’s demands are absolute (subject only to defences), while other reasons more readily give way to competing reasons.]
Notes
I. OBLIGATIONS IN THE LAW
ii. What accounts for the stringency of legal obligations?
Sanction:
- Austin & Kelsen? (where do they differ?)
- Command theory?
- Kelsen’s sanction theory?
- Austin and Kelsen both thought that sanction was behind legal obligations, though Austin envisaged a direct connection while Kelsen envisaged an indirect one
o Command theory: Austin defines command as an expression of will coupled with an attached risk, however small, of suffering an evil for non-compliance. This risk of sanction accounts for the stringency of obligations: “When I am talking directly of the chance of incurring the evil … I employ the term duty, or … obligation”.
o Kelsen’s sanction theory: Kelsen objects to the command theory and the content of a legal duty to be only part of a triggering condition for the mandatory norm which commands or authorizes officials to impose a sanction. “[A] norm: ‘You shall not murder’ is superfluous, if a norm is valid: ‘He who murders ought to be punished. [Thus,] legal obligation is not, or not immediately, the behavior that ought to be. Only the coercive act, functioning as a sanction, ought to be.”
