body: Watching the People's Court, the judge says the plaintiff has a responsibility to mitigate their damages. 
  
  
  In other words the (People's) court holds the plaintiff to a standard of effort when they have lost money and are suing to get the money back.
  
  
  My question, is this standard in the (People's) court part of contract law, or is it a legal standard the court uses in the administration of the law --and possibly open to (greatest) judicial interpretation? Or is it some reasonableness made up for television?
