A 'Mistake of Law' refers to a misunderstanding or ignorance of the law, which typically does not excuse a person from liability for violating the law. This principle is grounded in the legal maxim 'ignorance of the law is no excuse,' emphasizing the expectation that individuals are aware of legal obligations and prohibitions.
Public policy refers to the system of laws, regulatory measures, courses of action, and funding priorities set by a government or its representatives. It shapes societal outcomes by addressing public issues through strategic planning and implementation, often reflecting the values and priorities of the governing body.
