A contractor's motion for summary judgment on government repayment claims was granted by the Armed Services Board of Contract Appeals because the government never specifically identified the work the contractor allegedly failed to perform. The contracting officer's final decision demanded repayment under two technical support contracts on grounds the contractor "failed to perform the prescribed work." On appeal, the contractor moved for summary judgment. The government maintained the contracts were firm fixed price, level-of-effort and the contractor did not expend the required level of effort.
