The Supreme Court on Monday will hear arguments in two cases challenging the Texas abortion law that bans most abortions after around six weeks of pregnancy.

The court will hear arguments in Whole Woman’s Health v. Jackson and United States v. Texas, both of which challenge the Texas abortion law.

On Monday, the court will deliberate on concerns around the structure of the Texas law rather than consider whether the law violates Roe v. Wade.

Texas Governor Greg Abbott signed the abortion ban into law in May. The law took effect in September and bans almost all abortions after a fetal heartbeat can be detected, at around six weeks of pregnancy. The law does not make exceptions for abortions in cases of rape and incest. The only time the law permits abortions is when the life of the mother is at stake or the pregnancy could cause “substantial and irreversible impairment of a major bodily function.”

In addition, the Texas law allows private citizens to launch civil lawsuits against anyone who “aids or abets” an abortion after a fetal heartbeat can be detected. At least one such lawsuit has already been filed.
