In 1980, two male laboratory technicians at Bellahouston Academy, Coles and Reid, subjected their female co-worker, Porcelli, to a campaign of vindictiveness, some of which was sexual in nature. In 1983, Porcelli transferred to another school and filed a complaint under the Sex Discrimination Act (1975). A Scottish Industrial Tribunal ruled that there had been no discrimination on the grounds of sex. Using a male comparator, it surmised that the two respondents would have treated a man equally badly. The Employment Appeal Tribunal overturned this decision. Although the sex Discrimination Act (1975) did not, in 1985, outlaw sexual harassment per say, it did outlaw the subjection of female employees to any "detriment" during the course of employment. Forcing Porcelli to transfer to another school in order to escape from sexual harassment in her own school was founded to constitute such a detriment. Therefore, in these circumstances, sexual harassment amounted to discrimination on the ground of sex. (Porcelli v Strathclyde Regional Council (1985) CR 177,  IRLR 467).
In 2002, the Equal Treatment Directive (76/207/European Economic Community) was amended to include definitions of harassment as sexual harassment. The U.K. is subject to EEC directives. By 2005, the Sexual Discrimination Act will have changed to reflect the amendments to the Equal Treatment Directive.
