What does self-induced intoxication fail to provide a defense for, according to R v. Caldwell?

In R v. Caldwell, the court established important principles regarding self-induced intoxication, particularly how it impacts the mens rea required for certain offenses. The ruling clarified that while self-induced intoxication might serve as a defense for specific intent crimes—where the intention to achieve a particular result is necessary—it does not suffice as a defense for crimes that can be committed with recklessness as the mens rea.

When a crime requires recklessness as its mens rea, the defendant's intoxication does not negate their recklessness. Under the Caldwell standard, a person is reckless if they perceive a risk but proceed anyway, or if they fail to recognize an obvious risk that a reasonable person would have recognized. This means that individuals cannot escape liability for their actions simply because they were intoxicated at the time.

Thus, the correct understanding is that self-induced intox
