JCT Forms of Contract try to ensure that, when works have been completed, outstanding disputes can be rapidly and finally resolved.
In part this is by the employer’s agent issuing a Final Certificate, whereupon the contractor (and sometimes the employer) has 28 days to challenge it.
In the absence of a challenge, the Final Certificate becomes conclusive evidence for a wide range of issues, including defects, delays and outstanding cash disputes.
In the High Court case of Marc Gilbard 2009 Settlement Trust (trustees of) v OD Developments and Projects Ltd  the claimant employed the defendant contractor to carry out works. The contract incorporated the JCT Standard Building Contract, Without Quantities, Revision 2 (2009).
The Contract Administrator issued a Final Certificate showing the defendant owing the claimant £232,153.54 plus VAT.
Within the relevant 28 day period, the defendant issued Part 7 proceedings in the Technology and Construction Court disputing the validity and correctness of the Final Certificate. Those proceedings had proceeded so slowly that, 13 months on, the first Case Management Conference had yet to be scheduled.
The defendant now wished the issues raised in the Part 7 claim to be referred to adjudication.
The court said the real interpretation issue was whether clause 1.9.3 of the contract envisaged:
1. one set of proceedings (whether adjudication, arbitration or court proceedings) issued within the 28 days to challenge the Final Certificate, or
2. an initial set of proceedings in which the relevant “matters” could be raised, but then allowed the challenger to commence other proceedings, beyond the 28 days, which would be equally legitimate so long as those same matters were raised in those later proceedings.
The court ruled that interpretation 1 was the correct interpretation. The purpose of clause 1.9.3 was to limit issues for which the Final Certificate was not conclusive to matters raised in any proceedings issued within the 28 days of that certificate.
The clause assumed that the party challenging the Final Certificate could choose the venue in which that was to be done. It could choose one of adjudication, arbitration or other proceedings (that’s to say in court).
The clause did not envisage more than one set of proceedings.
Nothing in clause 1.9.3 allowed a series of subsequent proceedings, with the first being commenced within 28 days, and the others starting months or years afterwards.
However if adjudication is the first option of a challenger under clause 1.9.3:
A. a challenger under clause 1.9.3, can within the 28 days issue simultaneous protective arbitration or court proceedings. This would protect the challenger’s position if they have messed up the reference to adjudication or the outcome of adjudication was no decision or a decision which is unenforceable; and/or
B. clause 1.9.4 of the JCT provisions allows 28 days more for a party to issue arbitration or court proceedings to challenge an adjudicator’s decision as to the Final Certificate.
But, if arbitration or court proceedings are the first option of the challenger, or if the challenger messes up the reference to adjudication, a party may end up out of time to challenge the Final Certificate.
Subject only to the qualifications at A and B above, the challenger has to challenge the Final Certificate in one set of proceedings, and those proceedings are the only means by which the Final Certificate can be challenged.
The JCT Design and Build Contract has a provision very similar to clause 1.9 which additionally and usefully allows the employer or contractor, before the final date for payment, to give notice “disputing anything in the Final Statement”.
The moral of this case is, if you are thinking of challenging a Final Certificate, to act without delay within the 28 day period to secure your position as above.
