73.—(1) Contracting authorities shall ensure that every public contract which they award contains provisions enabling the contracting authority to terminate the contract where—
(a)the contract has been subject to a substantial modification which would have required a new procurement procedure in accordance with regulation 72(9);
(b)the contractor has, at the time of contract award, been in one of the situations referred to in regulation 57(1), including as a result of the application of regulation 57(2), and should therefore have been excluded from the procurement procedure; or
(c)the contract should not have been awarded to the contractor in view of a serious infringement of the obligations under the Treaties and the Public Contracts Directive that has been declared by the Court of Justice of the European Union in a procedure under Article 258 of TFEU.
(2) Those provisions may address the basis on which the power is to be exercisable in those circumstances, for example by providing for notice of termination to be given and by addressing consequential matters that will or might arise from the termination.
(3) To the extent that a public contract does not contain provisions enabling the contracting authority to terminate the contract on any of the grounds mentioned in paragraph (1), a power for the contracting authority to do so on giving reasonable notice to the contractor shall be an implied term of that contract.
