The DCMA-enforced CPSR requirement that contractors check sam.gov prior to subcontract award has always bothered me. Not because it's not a good business practice, but because contractor sam.gov checks are not a requirement per FAR Part 52.209-6. Because debarment is a public law, a DCMA finding of noncompliance with the (imaginary from a regulatory perspective) sam.gov requirement can lead to system failure without additional findings.
