No later than fourteen (14) days prior to the date set for any hearing, each party will submit to the other copies of all documents, reports and records relevant to the dispute. Failure to submit such documents, reports and records no later than fourteen (14) days prior to the hearing will preclude the non-complying party from submitting such documents, reports and records into evidence at the hearing, but the other party will have the opportunity to examine such documents, reports and records at the hearing and to introduce those it desires into evidence, except that relevant documents submitted to the opposing party less than fourteen (14) days before the hearing will be admissible provided that the proffering party and the custodian(s) of the documents made a good faith effort to obtain (or discover the existence of) said documents or that the document’s relevance was not discovered until the hearing date. In the case of an expedited grievance pursuant to Section 4, such documentary evidence shall be exchanged on or before two (2) days prior to the date set for the hearing unless the arbitrator indicates otherwise.
