Pursuit of Justice is a talent in the Retribution tree, and one will need to spend 7 points in Retribution to max it.
This is a very popular talent for PvP Paladins due to their lack of notable ranged attacks and because they only have either one, or a maximum of two, attacks that can slow down their opponent (Hammer of Justice for all specs including Holy; and either Repentance for Retribution, or Avenger's Shield for Protection).
Pursuit of Justice is also a popular paladin tank talent, for those that go this far into the Retribution tree. The disarm duration reduction helps out since a lot of raid and heroic mobs have disarm, and the 15% speed is helpful in moving around for positioning which a tank has to do often in some boss fights.
Edit
Patch 3.2.0 (2009-08-04): This talent will no longer sometimes be deactivated when leaving a battleground. 
Patch 2.3.0 (2007-11-13): Is now 3 ranks and increases movement speed by 5/10/15% and also reduces the chance you'll be hit by spells by 1/2/3%.
