The Court of Federal Claims found no rational basis for transferring a requirement for laundry services to the AbilityOne Procurement List in violation of guidelines that implemented contracting preferences under the Veterans Benefits Act, because the guidelines were entitled to deference and properly gave priority to the VBA over the Javits-Wagner-O'Day Act. In the protest by the incumbent contractor, the government did not dispute the contracting officer's decision to place the requirement on the AbilityOne Procurement List violated the Department of Veterans Affairs' new guidelines, which required COs to research whether service-disabled veteran-owned or veteran-owned small businesses could perform needed services before recommending a new requirement for the AbilityOne Procurement List. The list, established under the JWOD Act, consists of products and services that must be purchased from qualifying nonprofit entities that employ people with disabilities.
