In 1986, the Irish government put the issue up to a nationwide referendum, but 63.5 percent voted against amending the constitution. A law allowing legal separation passed in 1989. After coming to power in 1994, a “Rainbow Coalition” government composed of center-left parties once again propagated a referendum on amending the constitution to allow divorce.
Both Pope John Paul II and Mother Teresa publicly endorsed the “No” side, a sign of the seriousness with which the Church opposed this perceived challenge to its authority. Nonetheless, the Church conceded that it would not be a sin for Catholics to vote “Yes.” Ultimately, the “Yes” campaign ran up huge numbers in urban areas, winning by the razor-thin margin of 50.3 percent to 49.7. Numerous attempts were made to challenge the result, but to no avail.
Although the 1995 referendum only legalized divorce in cases where couples had been separated for at least four years, proponents of the separation of church and state hailed it as a victory to build upon.
“We’re bringing Ireland into the 20 Century at the dawn of the 21,” said Mags O’Brien, a pro-divorce campaigner. Similarly “overdue” reforms would follow. 2015 saw the legalization of same-sex marriage with 61 percent of the vote, and 66 percent of voters approved an amendment to legalize abortion in 2018. In 2019, another amendment greatly relaxed the requirements for obtaining a legal divorce, doing away with the period of separation.
