News & Events


In February 2019, we wrote an article headed “Approbation and Reprobation in Adjudication - Another Jurisdictional Challenge Fails” in which we made the point that parties regularly challenge an adjudicator’s jurisdiction. Hitachi was no different in the case of Hitachi Zosen Inova AG v John Sisk & Son Limited

Approbation and Reprobation in Adjudication – Another Jurisdictional Challenge Fails [February 2019]

As a means to resist enforcement of an adjudicator’s decision, or otherwise frustrate the adjudication process, parties regularly challenge an adjudicator’s jurisdiction. The first challenge is often that the referring party has not followed the correct procedure in appointing the adjudicator. However, a party cannot “blow hot and cold” in asserting an adjudicator’s decision is valid for one purpose while also challenging its validity for another; a principle known as approbation and reprobation (“A/R”).

A cautionary tale on working under letters of intent [November 2018]

It is not uncommon for contractors to start work on the basis of a letter of intent and to postpone the agreement of contract terms to a later date. In some cases, despite terms going back-and-forth between the parties, a formal contract never materialises but the work continues nonetheless. This can prove to be a risky approach, as to which Arcadis v AMEC serves as a cautionary tale.


In March 2018, we wrote about the case of Grove Developments v S&T, in which The Hon Mr Justice Coulson held that an employer whose payment notice or pay less notice was deficient or non-existent could, by way of an adjudication, dispute that the sum paid was the ‘true’ value of the works for which the contractor had claimed.


Many employers, contractors and subcontractors will be able to relate to, and likely remember, those projects which were subject to long delays for various reasons. In a main contract, for example, the contractor may be responsible for some of the delays experienced while the employer may be liable for other delays, some occurring concurrently. In those circumstances, the vexed question often asked is: “Is the contractor entitled to an extension of time?”

Hats off to the Kerrigans’ team

2015 has been a successful year for the Kerrigans’ team in gathering educational, legal and professional qualifications. In particular, Kerrigans would like to take this opportunity to congratulate:

Kerrigans - 25 years of legal excellence

On the evening of 2 October 2015, clients, fellow practitioners, friends and family came together with Kerrigans at a venue overlooking the Liverpool waterfront to celebrate its 25 years of service to the construction industry which Peter Kerrigan, the managing director of Kerrigans, described as “having gone in a heartbeat”.
