Neil O'Donnel and Dennis Callahan discussed the Supreme Court's decision to hear an appeal by the contractors in one of the largest and longest running cases in Government contracts history – the challenge to the Navy's 1991 termination for default of the contract for the development and prototype production of the A-12 stealth aircraft. The article examines the potential impact of the case with regards to two issues decided by the Federal Circuit: (1) the standards governing terminations for default, which the Supreme Court refused to consider, and (2) the application of the state secrets privilege in government contracts disputes, which the Supreme Court will review. FEATURE COMMENT: The "A-12 Saga Continues (PDF) The Government Contractor, Vol. 52, No. 45 - December 8, 2010.
