An example of ex post facto law?

Answer:
An example would be if a woman was driving in Illinois and the speed limit was 50mph. So she drove exactly 50mph. The passing police officer checked her speed and insured that she was going the good speed. The next day, Cpngress decided to lower the speed limit to 40mph. That afternoon, that woman was driving 40mph. The police officer checked her speed and insured that she was going the good speed. THEN he remembered that she was driving 50mph yesterday and pulled her over. He would try and give her a ticket for speeding. Get it? You're getting punished for a law after the fact.

It is meant to prevent a law being passed to make a past action illegal. Some countries will discover an action they do not like, but is not against the law. So they pass the law to make that action illegal and then apply it to people that broke that law before it was passed.
