Answer:
Money damages are awarded by the court to make defendants pay you money to make up for harm you suffered in the past. Punitive damages may be awarded to punish defendants for especially bad conduct.
An injunction is a court order that directs prison officials to make changes in your prison conditions and/or stop ongoing conduct that the court finds to be illegal.
A declaratory judgment is when a court makes a decision that explains your legal rights and the legal duties and obligations of the prison officials. However, the court doesn’t order the prison to do or stop doing anything. If you get a declaratory judgment and the prison doesn’t follow it, you can then ask the court for an injunction to make them do so.
