Definition - What does Mandate mean?
A mandate is a non-optional order that is given by a court. Mandates are often given by superior courts to lower courts.
Mandates are legally enforceable, and people or organizations who are given mandates by the courts are required to comply to them. If they don't then, legal consequences could follow.

Essentially, mandates are a way for courts to give formal instructions or orders to the people or courts that need to have this information.
