Section 4: Players & Officials
Referee: the DRA Rule Book defines the Referee as the Official appointed to take charge of Match play at a Match board or on stage during a Darts Event. The Referee acts as umpire in all matters pertaining to the General Playing Rules, consulting Scorers and other Officials where necessary before announcing decisions (Rule 6.4.10), and has the final say on all matters relating to starting and finishing a leg (Rule 6.3.12).
Second Referee (Rule 6.7.7): where appointed, a Second Referee's powers are as wide-ranging as the Referee's, but in practice they specifically supervise scoring corrections, the Exclusion Zone, and general player behaviour out of the primary Referee's sight. The Referee retains primacy over all decisions, with the Second Referee acting in an assisting and advisory capacity.
Marker (also "Scorer"): a person appointed by the Promoter to mark scores during a Match. Darts may only be retrieved from the board by the throwing player once the Referee has called, or the Marker has recorded, the score for that visit (Rule 6.4.3).
Tournament Director: the person appointed by the Promoter to oversee the running of a Darts Event. The Tournament Director rules on dartboard-change requests where the parties disagree (Rule 6.5.11), determines disqualification for breaches of the General Playing Rules (Rule 6.1.7–6.1.11), and adjudicates matters of Playing Attire (Rule 6.17.1, 6.17.6).
Promoter: any organisation or individual promoting or organising a Darts Event under DRA Rules. The Promoter's decision on all matters pertaining to the General Playing Rules during an event is final and binding (Rule 6.8.3), and the Promoter performs the event draw (Rule 6.12.1).
Darts Regulation Authority (DRA): a company limited by guarantee, registered in England (company number 4509423), governed by a Board of up to five independent members. The DRA Board delegates disciplinary matters to a Disciplinary Commissioner (Rule 9) for allegations of Minor Misconduct, and to the Disciplinary Committee (Rule 10), chaired independently, for Non-Minor and Serious Misconduct, with a route of appeal to an Independent Disciplinary Panel or Appeals Committee (Rules 16–17).
