In early 1971 Senator Mary Robinson (who would later become president) attempted to introduce the first bill proposing to liberalise the law on contraception into the Seanad, but was not allowed a reading, so it could not be discussed. On 31 March a number of supporters managed to get into the grounds of Leinster House and then broke into the building to register their protests. On 22 May 1971 a group of Irish feminists including Mary Kenny travelled to Belfast by rail and made their return to Dublin Connolly, laden with contraceptive devices, into a statement on the illogicality of the law. This provoked criticism from the Roman Catholic Church in Ireland; Thomas Ryan, Bishop of Clonfert, said that ""… never before, and certainly not since penal times was the Catholic heritage of Ireland subjected to so many insidious onslaughts on the pretext of conscience, civil rights and women's liberation.""
