Save Share A Federal Court judge has slammed delays by big four consultancy Deloitte in producing evidence in a landmark age discrimination case as âbizarreâ and not âsensibleâ. Deloitte partner Colin Brown is suing the firm. Deloitte also revealed in court on Wednesday that another 29 retired partners may be affected by the action, in which audit partner Colin Brown alleges the firm has a policy of making partners retire at 62, in breach of the Age Discrimination Act. But Deloitteâs barrister said the consultancy was not able to meet the deadlines to produce this evidence given it covered 29 partners and a further 33 people with whom they might have discussed their retirement.
