A 2006 report by Animal Aid called the Act a "vivisectors' charter", alleging that it allows researchers to do as they please and makes them practically immune from prosecution. The report said that licences to perform experiments are obtained on the basis of a "nod of approval" from the Home Office Inspectorate, and that the Home Office relies on the researchers' own cost-benefit analysis of the value of the experiment versus the suffering caused.
