"A full pardon, which doesn't cover this."
A pardon was a formal forgiveness of a crime and associated penalty.

In 2374, Gowron pardoned Grathon Tolar, an expert in holographic forgery who was being held in a Klingon prison, in order to assist Captain Sisko in bringing the Romulan Star Empire into the Dominion War on the side of the Federation. (DS9: "In the Pale Moonlight")
In 2401, retired Admiral Jean-Luc Picard and the command crew of the USS Enterprise-D were pardoned for their crimes, including the hijacking of the USS Titan-A, for their role in saving the Federation from the Borg threat on Frontier Day as revealed by Tuvok to Seven of Nine. Along with pardoning Seven for her own actions, Starfleet Command officially promoted her to Captain of the rechristened USS Enterprise-G based on a recommendation from Liam Shaw recorded before his death.
