Tbe struggle for the liberalization of the law on abortion began in Belgium in 1970 when the taboo was breached in an initial bill. However, support by pressure groups failed and this led to a long period of nondecision, which may be explained by the disunity in the camp of the supporters on the one hand and the blocking tactics of the Flemish Christian Democrats on the other. In 1986 a compromise between supporters finally emerged, and via a majority which cut right through the governmental coalition an abortion law was approved at the end of March 1990, which closely corresponds to British, French and Dutch legislation. The catholic monarch's refusal to ratify the bill caused a political crisis which was solved by the unanimous signing by the assembled ministers.
