In 1976, the NCCL in a submission to the Criminal Law Revision Committee of the British Parliament argued that "Childhood sexual experiences, willingly engaged in, with an adult result in no identifiable damage… The real need is a change in the attitude which assumes that all cases of paedophilia result in lasting damage". The NCCL also sought to place the "onus of proof on the prosecution to show that the child was actually harmed" rather than having a blanket ban on child pornography and advocated the decriminalisation of incest.
