Former ALRANZ president Margaret Sparrow established a non-profit company called Istar to import mifepristone (formerly known as RU 486), a pill used in medical abortions to cause the embryo to dislodge from the uterine wall, and a prostaglandin supplement to expel the remains. In 2002, Istar convinced the Abortion Supervisory Committee to seek a Court ruling on how the CS&A Act 1977 applied to the use of mifepristone. In April 2003, Justice Durie ruled that women seeking medical abortions must take medications in a licensed facility but need not remain there between taking the two sets of tablets, which are taken 48 hours apart. Women also need not stay in the facility until the expulsion of the fetus completes the abortion.
