it literally, it literally means produce the body  only you can't simply, well the difference between a constitutional system and er an arbitrary government is that in arbitrary governments people get arrested and disappear, locked up, throw away the key and worry about it the next generation or after the next er military coup or whatever  but in a constitutional government there have to be procedures and one of the safeguards of individual liberty is that if you're ever arrested and detained by law enforcement agencies you have to be produced before a court within a specified period and charged with something.
