When will involuntary intoxication not be available, and what facts will be a tip off to this?
Not available where the intent was not formed by the intoxicated state, but rather their desires and tendencies toward the behaviour
Is involuntary intoxication available where the defendant underestimates the strength of their own drink?
No
However, what occurs where the intoxication is part voluntary and part involuntary, i.e. defendant was drinking but was also spiked?
The court will consider the effect of each aspect on the conduct
Will voluntary intoxication by a dangerous substance negate mens rea?
Only if the offence is one of specific intent
In what specific intent situation will a voluntarily intoxicated person still be guilty?
Where they become intoxicated only to gain the courage to commit the offence
Why is intoxication not a defence to strict liability offences?
Because strict liability offences have no mens rea requirement

What are the three requirements for the defence of necessity?
- Act was required to avoid an inevitable evil
- Defendant only did what was reasonably necessary
- What they inflicted was not disproportionate to what was avoided
What offence is necessity not available for, and what is the effect of this?
Murder, therefore if someone is faced with the choice of killing another or dying/being killed themselves, the law will not excuse them if they do not sacrifice themselves.
Law technically silent on whether necessity is available for attempted murder.
