Magistrate

A magistrate was a public official similar to a judge. Several worlds used magistrates in their justice systems.

Bajor
In 2369, a Bajoran magistrate named Faren Kag informed Deep Space 9 that there was a medical emergency in his village and requested assistance. Commander Sisko sent Doctor Bashir and Chief O'Brien to aid the emergency. 

When Odo placed Nog and Jake in a cell, the Changeling told Nog he would be facing the magistrate for allegedly breaking into the quarters of a Tholian ambassador. 

In 2372, Quark tampered with the replicators on the USS Defiant (2370) and Deep Space 9, causing users of the replicators to see advertisements for his bar. While Quark attempted to rationalize and play down his actions, Odo sarcastically reassured him, "I'm sure the magistrate will take that into consideration when he calculates your fine." 

In 2373, Odo told Quark he should keep his excuses for the magistrate, when one of Quark's under maintained holosuites had injured Benjamin Sisko. 

In 2375, the Changeling Laas got into a fight with several Klingons aboard DS9 and killed one of them. General Martok requested that Laas be detained until the magistrate could determine whether to honor the Klingon Empire's request that Laas be extradited to their jurisdiction.
