What is his role with regards to heraldry?

The Earl Marshall's role in heraldry is, firstly, as judge of the Court of the Earl Marshall, the Court of Chivalry. He determines and acts as the judge in his court between disputing parties over coats of arms. Usually, he would appoint a surrogate to act as the judge, in fact, because he's not necessarily legally trained. Secondly, he has to issue a warrant for any grant of a coat of arms to take place. He would direct the Kings of Arms, who are officials at the College of Arms, to make the new grant of arms. Thirdly, he specifies what the fees to be charged are for all of these official activities.
