In June 2016,
John Nicolson MP introduced a
Private Member's Bill, the Sexual Offences (Pardons Etc.) Bill 2016–17, intended to implement the proposal. In October 2016, the
Conservative government announced that, instead of supporting the Private Member's Bill's original proposal for a blanket pardon for all, it would enact the proposed changes through an amendment to the forthcoming
Policing and Crime Bill 2016. This amendment would provide a posthumous pardon for the dead, make it easier for living individuals to clear their names, and also provide an automatic formal pardon for living people who had had such offences removed from their record through the disregard process. When Nicolson's bill was debated in Parliament on 21 October 2016, it was successfully
filibustered by Conservative MP
Sam Gyimah and failed to proceed. The two differed in the process for dealing with cases where the conviction was for an act that would still be considered an offence under current law. Both attempted to exclude these, but Nicolson's bill provided an automatic pardon while the government bill required the petitioner to go through the "disregard process" first. This would mean that the
Home Office will investigate each case involving living people to ensure that the act that the petitioner was convicted of is no longer considered a criminal act, to avoid pardoning men convicted of
underage sex or rape. The government claimed that without this check, men who were convicted of such an offence would be able to claim that they had been pardoned. The Nicholson bill would not have been able to clear criminal records of men who still carried convictions. This would still have to be done through the disregard process, leading to possible cases in which it would not be clear whether or not a pardon had been granted, described by James Chalmers,
Regius Professor of Law at the
University of Glasgow, as a "
Schrödinger's pardon". On 19 October 2016, Liberal
Baron Sharkey, with government support, had added the core amendment to the agenda for the Policing and Crime Bill 2016. The Commons agreed to the relevant Lords amendments on 10 January 2017 and the bill received
royal assent on 31 January 2017 as the Policing and Crime Act 2017. and on 28 June 2018 in Northern Ireland. The provisions were not extended to Scotland because
the Scottish government was planning a similar measure, == Reaction ==
