2. ELIGIBILITY TO COMPETE IN CALENDAR FIXTURES

(a) MEMBERSHIP OF THE CROQUET ASSOCIATION
(1) Subject to (a)(2) and (3) below, only Life Associates and Associates who pay the Standard, Veteran, Junior, Youth or Overseas subscription rates may compete in calendar fixtures.
(2) The Council may remove this restriction from certain calendar fixtures ("exempt fixtures").  The names of any exempt fixtures shall be published in the C.A. Calendar.
(3) Non-Associates and Associates who pay the Non-Tournament subscription rates are also entitled to play in one calendar fixture other than an exempt fixture.  Thereafter, if such an individual wishes to compete in a calendar fixture other than an exempt fixture, he must comply with (a)(1) above.
(b) PROFESSIONALS
(1) A professional croquet player ("a professional") may not compete in a calendar fixture if notice has been given in the tournament programme in accordance with Regulation 19(a)(2) that professionals are excluded therefrom.
(2) A professional is defined as a player who has received and retained total prize money (including appearance money) exceeding the aggregate prize limit in the twelve months preceding the relevant calendar fixture.
(3) The aggregate prize limit will be determined from time to time by the Council and published in the C.A. Calendar.
(c) DOPING
(1) Doping is forbidden.  A player who uses any substance or procedure included in the International Olympic Committee Medical Commission list of prohibited doping classes or methods in
(A) competitions designated by the Council; or
(B) other calendar fixtures, where the substance or procedure has not been prescribed by a doctor, is automatically disqualified from competing in calendar fixtures until the Council removes the disqualification.
(2) The identification of a forbidden substance and/or a substance produced in the body from such a substance, or the presence of specified amounts of natural body substances, in a body fluid will constitute an offence as defined in (c)(1) above.  Caffeine is deemed to be a natural body substance for these purposes.
(3) A player must, if requested by an official designated by the Council for the purpose of doping control, submit to a doping control test. If the result of the doping control test is positive, the player will be subject to the doping control procedure laid down from time to time by the Council and published in Croquet.  A player who refuses to submit to a doping control test will be treated as if a positive result had been obtained and will be dealt with accordingly.
(4) A person who assists or incites another to contravene the doping regulations may be subject to disciplinary action.
