A sex worker is using European human rights legislation to try to overturn a new law in Northern Ireland that makes it illegal to pay for prostitutes. Dublin-born law graduate Laura Lee is launching an unprecedented legal challenge, which could go all the way to Strasbourg, against a human trafficking bill that includes banning the payment for sex among consenting adults. The region is the only part of the UK where men can be convicted of paying for sex. The law, which was championed by Democratic Unionist peer and Northern Ireland assembly member Lord Morrow, comes into effect on June 1. Lee said she would launch her case at the high court in Belfast in the same month as the law comes into effect. The justice minister, David Ford, has already warned that the Police Service of Northern Ireland may not be able to convict men contacting prostitutes for sex because intercept evidence from clients' mobile phones would be inadmissible. "I am doing this because I believe that when two consenting adults have sex behind closed doors and if money changes hands then that is none of the state's business," Lee, 37, said. "The law they have introduced has nothing to do with people being trafficked but simply on their, the DUP's, moral abhorrence of paid sex. "Sex workers' lives in Northern Ireland will actually be harder and the industry will be pushed underground." Lee said her legal team would be referencing several articles of the European convention on human rights to challenge and overturn Morrow's law. Lee said she would fund the case partly via crowd funding on social media networks and from sex worker campaign groups across the world. Lee, an Irish psychology graduate whose range of services include S&M and bondage, said she was also taking the legal challenge to thwart an attempt to introduce a similar law criminalising the consumers of sex in the Irish Republic. Morrow defended his bill and criticised any move via the courts to overturn the legislation. "If Europe or any other court did this they would be ignoring the will of the people and the overwhelming majority of those in the Northern Ireland Assembly," he said.
