What does DC mean legally?

Excuse me, I'm a bit confused about a legal term that I've come across recently. Could you possibly explain to me what the abbreviation "DC" stands for in a legal context? I've tried to do some research on my own, but I'm finding the definitions quite varied and am hoping for a clearer understanding. It seems to have something to do with the court system or perhaps with criminal proceedings, but I'm not entirely sure. Would you be able to provide some insight? Thank you in advance for your help.
