P.R. Laws tit. 16, § 971f
Duly registered political parties may participate in the Referendum provided their central governing bodies report said intention to the Commonwealth Elections Commission within fifteen (15) days following the date of effectiveness of this act stating the option they shall support. Likewise, any bona fide citizen groups may participate as observers provided they comply with the requirements to such effects provided by the Commission by means of regulations. The Electoral Commission shall provide, by means of regulations, the level of participation of these groups in the Referendum process, as provided in Act No. 4 of December 20, 1977. Citizen groups that wish to participate shall report to the Commonwealth Elections Commission as to their intention within fifteen (15) days following the notice issued by the President of the Commonwealth Elections Commission to such effects. All parties that notify the Commission of their intention of participating in the Referendum shall be entitled to representation in the polling sites, as provided by the Electoral Law. If within the term established herein no party notifies its intention to participate in the Referendum, the Commission, by means of regulations, shall establish a procedure to grant to some civic or political group, the representation of any of the proposals in the polling sites on the day the Referendum is to be held. The Commission shall also establish the procedure to be followed, so that on the day of the Referendum, any voter may represent in his/her polling sites the proposal of his/her preference or his/her political party, if the same lacks representation therein.
