Tailoring clause 52.212-4 for unilateral modifications in Contract Administration Posted December 17, 2018 · Report reply On 12/15/2018 at 8:39 PM, Jamaal Valentine said: Then we need to review how unilateral actions like exercising options, issuing terminations, etc. are proper in light of 52.212-4(c). If these unilateral actions are permitted, it's reasonable to believe administrative changes that don't alter the terms and conditions of the contract in ways that affect the substantive rights of the parties are also permissible. Jamaal, I don’t think that’s the right discussion to have. Are options and terminations governed by 52.212-4(c)?
