Foreigners Refugees or Minorities? : rethinking people in the context of border controls and visas by UK Race Relations Act & amendments and the Equality Act 2010
Commission for Racial Equality v Dutton [1989] IRLR 8 decided that a sign displayed in a pub saying “No Travellers” was discriminatory as Romany Gypsies are a racial/ethnic group
In O’Leary & Others v Punch Retail & Others (Westminster County Court 29 August 2000) Irish travellers challenged a “No Travellers” sign in a pub.
Judge Goldstein at a preliminary hearing at Central London County Court in 2000 held that the Race Relations Act should cover Irish Travellers as an ethnic group. He pointed to their shared history: "Modern Irish Travellers are guided by the culture and traditions which have been handed down by generations. They do not go around reading history, they practise it."
