As it is said in the article "Civil and public law", civil law concerns disputes among citizens within a country, and public law concerns disputes between citizens and the state, or between one state and another. There are five categories of English civil law: contracts, torts, trusts, probate and family law. Crimes, constitutional law and international law are the main categories of public law. Criminal and civil procedures have differences. There are different names of parties bringing the action. Prosecution is the party bringing a criminal action. And plaintiff is the party bringing a civil action. Though in both cases the other party is defendant. Another difference is that the standards of proof are higher in a criminal action than in a civil one. The point of contact is that the civil case may continue as a criminal prosecution.
But it would be perfect if we didn't need to appeal to any of these law institutions at all.
