(a) Whenever the rules of a party provide that a candidate for delegate or alternate delegate to a National convention of a political party may pledge his support to a presidential candidate, he shall be committed to support and vote for the nomination of that candidate as president as party rules provide, the notation of which shall be printed upon the ballot in accordance with section 1002 of this act.¹

(b) No candidate for delegate or alternate delegate shall make a commitment unless he has obtained prior authorization to do so from the presidential candidate to whom he is pledging support. No candidate for delegate or alternate delegate shall be allowed to commit himself to any presidential candidate nor shall the Secretary of the Commonwealth cause any notation of commitment to be printed on any ballot unless the presidential candidate forwards notice to the Secretary of the Commonwealth, upon a form prescribed by the secretary, that he is a candidate for the nomination of President of the United States and that he authorizes delegates and alternate delegates to pledge their support and commit themselves to him. This notice must be received by the secretary at least fifteen days prior to the first day on which nomination petitions may be circulated for the offices which are to be filled at the Spring primaries in the years in which candidates for the President of the United States are to be nominated.

(c) Nomination petitions for delegates committed to particular presidential candidates shall be obtained only from the presidential candidate or his duly authorized representative who is certified by the Secretary of the Commonwealth as being authorized by the candidate to distribute nomination petitions bearing his name.
