英文中有ignorance of the law is no excuse，个人应该理解为“不知法不免责”好一些。

In law, ignorantia juris non excusat (Latin for "ignorance of the law excuses not"),[1] or ignorantia legis neminem excusat ("ignorance of law excuses no one"),[2] is a legal principle holding that a person who is unaware of a law may not escape liability for violating that law merely by being unaware of its content.

European-law countries with a tradition of Roman law may also use an expression from Aristotle translated into Latin: nemo censetur ignorare legem ("nobody is thought to be ignorant of the law") or ignorantia iuris nocet ("not knowing the law is harmful").
