The government filed claims against the estate based on government contracts with the debtor. Trustee filed this adversary proceeding objecting to the claims. Finding the case of In re Gary Aircraft Corp., 698 F.2d 775 (5th Cir. 1983) to be instructive, the court discussed primary jurisdiction and discretionary deferral of government contract claims disputes. The court concluded that deferral would unduly delay administration of the estate and denied the government's motion to dismiss or defer.
