This Practice Note considers the definition of the protected characteristic of sexual orientation for the purposes of protection from discrimination and other prohibited conduct under the Equality Act 2010 (EqA 2010), ie sexual orientation towards persons of the same sex, persons of the opposite sex, or persons of the same or opposite sex. It considers the guidance from case law, covering matters such as whether actual and/or perceived sexual orientation is protected and that while the definition of sexual orientation does not, by its terms, include sexual practices or sexual conduct, there will often be a correlation between certain types of conduct and particular sexual orientation and this may be protected. For a guide to all our materials relating to protections and liabilities arising out of acts and omissions that amount to sexual orientation discrimination or other forms of prohibited conduct that are connected to sexual orientation, which signposts fully detailed materials found in other Practice Notes that deal with each aspect of the subject matter in full depth, see Practice Note: Sexual orientation discrimination.
