Using Judgement is typically referred to as "Judging" a target. Judging a Seal a Paladin has cast on himself can result in a myriad of abilities, from damage to utility debuffs. If the Judgement is a debuff, the duration of it can be refreshed each time the Judging Paladin lands a melee hit.

The Tier 2 Paladin armor set is called Judgement Armor and includes an 8-piece set bonus that inflicts 60-66 additional Holy damage to the target a Paladin is Judging.
The set also offers a distinct and fitting look for Paladins and many Paladin-centric armor pieces in the Burning Crusade expansion have used variations of the Judgement set, normally a different color theme.
