There is a strong perception that Adjudicators are biased in favour of claimants, especially in the States using the 'East Coast' model of Security of Payment legislation. Claimants in these jurisdictions apply for adjudication of a payment dispute through an Authorised Nominating Authority rather than agree an Adjudicator with the respondent (as is the case in the 'West Coast' model). This perception is caused by the perceived ability for claimants to pressure ANAs into providing an Adjudicator that will favour the claimant's case.
