Abortion.

Defines viability for purposes of the abortion law as the earlier of the time of each postfertilization age of the fetus that is less than 21 weeks or the time of conception. Provides that the definition is severable to preserve the earliest possible time that viability is determined. Specifies that abortions are permitted in certain circumstances before the earlier of viability or the end of the first trimester of pregnancy. (Current law specifies that abortions are permitted in certain circumstances during the first trimester of pregnancy.)
