As a non-native speaker quite often I get in trouble with slight differences between concepts. So, regarding to this doubt I think both of them are used to express the same thing but I'm not sure about it.
After looking for an answer in my dictionary but having no answer, I was told by a lawyer (ESL-learner) that these two words are similar in the matter of laws. However, I wanted to make it clear.
Could anyone help me out?
