This chapter looks at the process of adjudication in construction industry disputes. Adjudication resembles arbitration, in that it produces a decision on the dispute, but one that is only of a temporary nature. The process involves an adjudicator reaching a decision very swiftly (only 28 days after appointment), with the idea being to get a decision on how much a contractor should be paid, potentially followed by a full-blown investigation through the courts or in a formal arbitration if either party does not agree with the adjudicator's decision. The underlying policy is ‘pay now, argue later’. An adjudication award is binding, but is not registrable as a judgment, unlike an award in arbitration. Instead, enforcement is through suing on the adjudicator's decision, often followed by the entry of judgment in default or an application for summary judgment.
