If the FAR states that micropurchase limits are different for hardware and service, how can a charge that falls within the limits be denied because of the 51% rule? For example, a program conducts market research to replace a faulty system and the best value for the government comes in at $3,600 total. The KO selects a vendor and proceeds with the work. When a GPC is used for payment, the charge is denied because the lawyers state that the vendor's line items include too much service ($2,300). Furthermore, the lawyer states that he considers the entire bill to be service due to the fact that 51% of the bill is service-related. If the charge falls within the FAR limits, how can they deem the entire bill to be service and nullified?
