Deed of variation extending an expired contract with no change notice
A deed of variation dated 15 May 2026 extends a contract that expired on 31 March 2026, adds 20% to the value, and the decision record states no contract change notice was published. Key values are in prose recitals. Expect three high flags.
Hazards
- retrospective_extension - The variation is dated after the contract had already expired.
- no_ccn_published - The document states that no contract change notice was published before the modification.
- wrong_legal_ground - The authority cites a modification ground that does not cover the change made.
- values_in_prose - Key values are embedded in running text rather than in a table.
- date_ordinal - Dates printed as 3rd March 2026.
