Records in this series reflect the activities of the Provincial Secretary, Party president, and other members in response to formal complaints submitted to the Party.

While informal complaints submitted by Party members are regularly received and replied to by the Provincial Secretary or by another relevant Party member, the NDP additionally has a formal complaints process in place, as outlined in the Party Constitution. Article 16.02 of the "Constitution of the New Democratic Party of British Columbia" (as amended, June 1999) states that a complaint "may be lodged with the Provincial President by any member or constituted body of the Party alleging a violation of the constitution or a statement or action resulting in severe and evident injustice to a member or constituted body of the Party." Complaints were to be submitted in writing with any pertinent evidence included, details of the events that gave rise to the complaint, and the remedy sought (article 16.04). Should the President be unable to resolve the matter equitably, a special panel could be appointed to mediate the dispute, and/or it could be referred to the Provincial Executive for consideration within 30 days (16.05). It was also "a breach of the principles and policies of the New Democratic Party for any member to seek redress for any complaint against another member or body of the Party through public notice or solicitation," (16.08), an act that items in this series suggest happened occasionally, leading to further complaints and mediation.

Complaints contained in this series are varied in the nature of the issue and in the amount of documentation accorded to each, but several cases revolve around allegations of irregular member sign-up practices during nomination periods, or other nomination irregularities. Items in this series include correspondence (predominant), notes, membership cards, memos and public communications, some clippings, and other related materials.
