Each party to the controversy shall submit a brief or statement on the unresolved issues in controversy to the other party, to each of the appointed members of the fact-finding panel and to the executive director at least 5 working days prior to the date of hearing. This period may be modified by the executive director if less than 10 days' notice of the hearing is provided. This brief or statement may contain statements, facts, precedents or other pertinent evidence to support that party's position on the issues in question. All issues to be heard in oral argument must be set forth in this brief or statement. If the fact-finding proceeding is unilaterally invoked, the non-invoking party must include in its brief or statement any new issues it will raise at the fact-finding proceeding. The party requesting fact finding shall submit with its brief the most recent collective bargaining agreement, if any, between it and the other party.
