I meant that in a very specific way. A "Constitutional Court" is what some countries have to verify the bills passed by Parliaments before they actually become laws.
Think of it as a filter, that filters out all the "crap"/unconstitutional bills that Congress, either out of stupidity, or intentionally, wants to pass.
But these laws can still be found unconstitutional by normal Courts, or the Supreme Court later. The point is to have this so you don't wait 10 years until you even have a judge say if it's constitutional or not, and to stop an out of control government that thinks it can pass whatever it wants, 2 days before Christmas or in New Year's Eve, when no one is paying attention.
By the time the Supreme Court rules on some of those, a lot of damage has already been done, those people might not even be in Congress anymore (so they don't care what they pass), or they probably passed many more laws such as that by then, too, so the Supreme Court will never keep up.
