According to "The Irish Times", "the polls taken at the time showed that, if anything, the end of the advertising campaign coincided with a halt in the slide of support for divorce". Because of the use of Government funds for one side of the campaign, a petition against the result was lodged by Des Hanafin, a Fianna Fáil Senator and chairman of the Pro Life Campaign, which was dismissed by the High Court on 9 February 1996. Hanafin appealed to the Supreme Court, which in June upheld the High Court decision. The High Court then endorsed the provisional certificate on 14 June 1996. President Mary Robinson signed the amendment bill into law three days later.
