Criminal Law Flashcards
What is criminal law?
A body of law that regulates what conduct is considered criminal (within a particular jurisdiction). It regulates the punishment of such conduct by defining rules that must be followed to hold a person criminally responsible for engaging in it
What is substantive criminal law?
Focuses on the “substance” of an offence, and what actions are crimes, and what the penalties should be. Can include definitions of crime, forms of criminal responsibility, grounds for excluding criminal responsibility, jurisdictions, basic principles etc.
What is procedural criminal law?
Sets the rules and processes through which the criminal justice system operates. Can include pre-trial proceedings, trial proceedings, and appeal and review proceedings
Where does civil law originate, and where is it practiced now?
Roman Empire. Is practiced generally in Europe now, as well as many states in Africa, Central and Latin America, and some of Asia.
Where does common law originate, and where is it practiced now?
England, through William the Conqueror and his “king’s courts”. Is practiced generally in the UK, USA, and their colonies.
What are some core features of civil law?
- Written (codified) laws take precedent
- Deductive (top down) approach
- No binding case law (jurisprudence)
What is the deductive (top down) approach?
Used in civil law jurisdictions, it finds relevant rules from a systemised legal code and applies them to the facts of the case at hand, thus solving the case
What are some core features of common law?
- Uncodified (judge-made) law takes legal precedent
- Inductive (bottom up) approach
- Binding case law
What is the inductive (bottom up) approach?
Finding similar cases, distilling judicial rationale (ratio decidendi) used to solve it, applying the same reasonings to the case at hand to solve it
In civil law systems, what is contained in the criminal code?
- A special part: containing crime definitions
- A general part: containing rules and principles that apply generally to all crimes in the special part
In civil law systems, what is contained in the criminal procedural code?
- The rules and procedures governing pre-trial, trial and appeal proceedings
- How crimes should be investigated, who the main actors are
What are some sources of criminal law in civil law jurisdictions?
(Most used):
Criminal code
Criminal procedural code
(Less used):
Sepcialised legislation on distinct crimes Constitution
Previous court judgements (not binding)
Legal doctrine (scholarly work, not binding)
What is jurisprudence?
The study and theory of law.
In common law, jurisprudence relies on interpreting case law and judicial precedents.
In civil law, jurisprudence revolves around interpreting codified statutes.
What is stare decisis?
Literally, to stand by things decided. Refers to the legal doctrine where courts follow precedents set by previous judicial decisions when ruling on similar cases. This ensures consistency and predictability in the law. Also says that higher courts have a higher power than lower ones.
What are some sources of criminal law in common law jurisdictions?
(Most used):
Legal precedents
Laws passed by parliamentary legislations
(Less used):
Statutory laws on specific crimes
Constitution (not in UK)
Modal penal code (not in UK)
There is no criminal code in the UK or USA
What is a monist system?
One in which a treaty becomes directly applicable to a system once signed
What is a dualist system?
One in which a treaty must be signed and ratified, AND the legislative body has to translate it into their own legislative system before being directly applicable to the system
What is the legality principle?
Also known as nullum crimen nulla poena sine lege, literally no crime, no punishment without the law. It states that a new criminal law in the criminal code cannot be applied to a modern crime that occurred before the law.
What are the key aspects of the legality principle?
A law should be:
1. Pre-existing (lex praevia)
2. Precisely formulated, not vague (lex certa)
3. Written (lex scripta)
4. Strictly interpreted and applied by courts (lex stricta)
What is lex praevia?
The principle of non-retroactivity. States that a person can only be convicted on the basis of a law that existed and applied to them at the time they engaged in the conduct
What is lex mitior?
If a law has been changed multiple times after an act was committed, the accused can benefit from the most lenient, favourable law, that was in use from the time the act was committed until the act is decided upon by the Court.
What is lex certa?
The prohibition of vague and indeterminate laws. Criminal law must be foreseeable and accessible to the accused at the relevant time.
What is the foreseeability element of lex certa?
The ordinary person must be able to understand from the wording of the law what conduct is illegal.
The law must be defined in precise and unambiguous language that narrowly defines the punishable offence
What is the accessibility element of lex certa?
The law must have been made public and available to the accused.
