The parties may request assistance from the Collaboration and Alternative Dispute Resolution Program (CADR) to attempt to resolve the dispute before or after an opposition is filed. Upon request, and as agreed to by the parties, CADR representatives will attempt to assist the parties to resolve these disputes. If the parties have agreed to CADR assistance, and the time for filing an opposition has not expired, then the Authority will toll the time limit for filing an opposition until the CADR process is completed. Parties seeking information or assistance under this part may call or write the CADR Office at 1400 K Street, NW., Washington, DC 20424. A brief summary of CADR activities is available on the Internet at http://www.flra.gov.
