The High Court has dealt a blow to mps involved with Michael Hopkins and Partners' Portcullis House after ruling them liable for using a buy- British policy for the facade. A judge said the House of Commons Commission should not have used the policy when it gave the contract to Seele Alvis, based in Britain and Austria. The case was brought by a US-based rival Harmon cfem Facades, which has since gone into liquidation. The judge held it was entitled to recover its tender costs of around £438,000 and any profit it could prove it would have earned. This will be determined at a later hearing.
