_________________________________________________________________________________________
173 In most contracts Relief Events should give only relief from the risk of termination for failure to complete or failure to perform. In cases in which liquidated damages are payable to the Authority there will be an issue of the extent to which relief can be given from claims for damages or liquidated damages. The performance regime should still apply and this should be made clear, to the extent there is potential for relief from liquidated and other damages.
