Arkansas Governor Asa Hutchinson (right) enacted a law on Tuesday that would automatically prohibit abortion if the US Supreme Court quashed its historic 1973 decision, Roe v. Wade, who legalized abortion in the country.
Hutchinson's office said the governor had signed the law, making it the fifth state with the so-called "abortion ban bill" triggered, reported the report. Associated Press agency.
The bills are based on the belief that a more conservative Supreme Court could overturn its ruling made 46 years ago and make the power to legalize abortion to states.
The law prohibits most abortions, except in the case of a medical emergency, if the country's highest court overrules its previous decision. The state currently prohibits abortion after 20 weeks of pregnancy.
Exceptions would not be allowed in case of rape or incest, KUAR reported.
The legislation was passed last week by the state legislature under Republican control.
Louisiana, Mississippi, North Dakota and South Dakota have similar "trigger" bans on books. A similar measure has recently been introduced in Kentucky and Tennessee.
