question: How are individual states able to make abortion illegal after the US Supreme court rulled that banning abortions was unconstitutional back in 1973..?
comment: So this is less about them being able to and more about them getting to challenge the Supreme Court's decision in Roe v Wade. Basically, these new laws are guaranteed to be challenged in federal court and will certainly make it all the way to the Supreme Court where these Republicans are hoping the conservative majority will choose to go against precedent and permit these extreme laws to go into effect. Short of holding a constitutional convention (which has lots of political risks for both sides) this is the only way for anti-choice conservatives to actually overcome Roe v Wade because Congress doesn't have the power to overrule the Supreme Court's ruling on constitutional subjects without changing the constitution itself.
passages: Abortion in the United States is legal via the landmark 1973 case of "Roe v. Wade". Specifically, abortion is legal in all U.S. states, and every state has at least one abortion clinic. However, individual states can regulate/limit the use of abortion or create "trigger laws", which would make abortion illegal within the first and second trimesters if "Roe" were overturned by the Supreme Court of the United States Also, nine states—Alabama, Arizona, Michigan, New Mexico, Oklahoma, West Virginia, and Wisconsin as well as the already mentioned Arkansas and Mississippi, still have their unenforced pre-"Roe" abortion bans on the lawbooks, which could start being enforced if "Roe" were overturned. In accordance with the US Supreme Court case of "Planned Parenthood v. Casey" (1992), states cannot place legal restrictions posing an undue burden for "the purpose or effect of placing a substantial obstacle in the path of a woman seeking an abortion of a nonviable fetus."
   BULLET::::- United States: "Ayotte v. Planned Parenthood of Northern New England", 546 U.S. 320 (2006), was a decision by the Supreme Court of the United States involving a facial challenge to New Hampshire's parental notification abortion law. The First Circuit had ruled that the law was unconstitutional and an injunction against its enforcement was proper. The Supreme Court vacated this judgment and remanded the case, but avoided a substantive ruling on the challenged law or a reconsideration of prior Supreme Court abortion precedent. Instead, the Court only addressed the issue of remedy, holding that invalidating a statute in its entirety "is not always necessary or justified, for lower courts may be able to render narrower declaratory and injunctive relief."
   The decision marked the first time the court allowed a ban on any type of abortion since 1973. The swing vote, which came from moderate justice Anthony Kennedy, was joined by Justices Antonin Scalia, Clarence Thomas, and the two recent appointees, Samuel Alito and Chief Justice John Roberts.
  
  Section::::State regulatory initiatives regarding abortion.
  
  The following states have or had initiatives regarding abortion. The fetal heartbeat bill legislative approach has picked up momentum in 2018 and 2019.
  
  Section::::State regulatory initiatives regarding abortion.:Alabama.
   The Court concluded that Texas's abortion statutes were unconstitutional, and struck them down: "A state criminal abortion statute of the current Texas type, that excepts from criminality only a life-saving procedure on behalf of the mother, without regard to pregnancy stage and without recognition of the other interests involved, is violative of the Due Process Clause of the Fourteenth Amendment."
  
  Section::::Supreme Court decision.:Concurrences.
   In August 2018, the dilation & evacuation (D & E) passed by Texas and Alabama were working their way through the federal courts appeal process. 
  
  Section::::History.:Funding history.
   Since the mid-1990s, the regulatory burden on abortion providers has increased. TRAP laws (Targeted Regulation of Abortion Providers) have been passed in numerous states. In 2015, the United States Supreme Court agreed to an emergency appeal regarding a Texas law that would have shut down 10 of the remaining 19 abortion clinics within the state. Sometime in the fall of 2015, the Supreme Court will decide whether or not to hear the clinics' full appeal of the ruling, which, if held, would be the largest abortion case before the Supreme Court in nearly 25 years.
   BULLET::::- "Planned Parenthood v. Casey", A woman is still able to have an abortion before viability, but several restrictions are now permitted during the first trimester. The strict trimester framework of "Roe" is discarded and replaced with the more vague "undue burden" test.
  
  BULLET::::- "Stenberg v. Carhart", Laws that ban partial-birth abortion are unconstitutional if they do not make an exception for the woman's health or if they cannot be reasonably construed to apply only to the partial-birth abortion procedure and not to other abortion methods.
   BULLET::::- The case of "Roe v. Wade" was reargued before the United States Supreme Court, after having first been argued on December 13, 1971, before seven Justices. While the initial opinion by Justice Harry Blackmun had simply found the challenged laws against abortion to be "unconstitutionally vague", the revised 1973 Blackmun opinion went further in declaring most restrictions against the right of choice to be unconstitutitional. "Had the Blackmun first drafts in the abortion cases come down as the final decisions", notes one commentator, "American life and politics might have been quite different."
   BULLET::::- "Ayotte v. Planned Parenthood of Northern New England", 546 U.S. 320 (2006), was a decision by the Supreme Court of the United States involving a facial challenge to New Hampshire's parental notification abortion law. The First Circuit had ruled that the law was unconstitutional and an injunction against its enforcement was proper.

Instead, the Court only addressed the issue of remedy, holding that invalidating a statute in its entirety "is not always necessary or justified, for lower courts may be able to render narrower declaratory and injunctive relief."
   In 1973, the U.S. Supreme Court decision "Roe v. Wade" legalized abortion nationwide. It established a minimal period during which abortion must be legal (with more or fewer restrictions throughout the pregnancy). This basic framework, modified in "Planned Parenthood v. Casey" (1992), is still in effect today. In accordance with "Planned Parenthood v. Casey", states cannot place legal restrictions posing an undue burden for "the purpose or effect of placing a substantial obstacle in the path of a woman seeking an abortion of a nonviable fetus." Although this legal framework established by the Supreme Court is very liberal (particularly with regard to the gestational age), in practice the effective availability of abortion varies significantly from state to state. 
   The U.S. Supreme Court debated its first abortion case. This covered the potential abolition of abortion laws in thirty nine states. These states only allowed abortion "when necessary for the preservation of the mother's health". The presiding judge determined that the law was vague and due to this was being challenged in Indiana, New Jersey, and Colorado. Judge Gerhard Gesell determined that the federal courts should return to existing abortion control laws in Minnesota, Missouri, Louisiana, Iowa, Massachusetts and Vermont.
  
  BULLET::::- January 24, 1971
   BULLET::::- 1973 - "Doe v. Bolton", 410 U.S. 179 (1973), was a decision of the United States Supreme Court overturning the abortion law of Georgia. The Supreme Court's decision was released on January 22, 1973, the same day as the decision in the better-known case of Roe v. Wade, 410 U.S. 113 (1973). Doe v. Bolton challenged Georgia's much more liberal abortion statute.
   Section::::History.:Judicial history.
  
  The US Supreme Court's decision in 1973's "Roe v. Wade" ruling meant the state could no longer regulate abortion in the first trimester. In August 2018, the dilation & evacuation (D & E) legislation passed by Texas and Alabama were working their way through the federal courts appeal process. The Eleventh Circuit ruled the D&E legislation to be unconstitutional, blocking it from being enforced, and the Supreme Court of the United States denied to hear its appeal in its 2019 term.
   Since Alabama introduced the first modern anti-abortion legislation in April 2019, five other states have also adopted abortion laws including Mississippi, Kentucky, Ohio, Georgia and most recently Louisiana on May 30, 2019
  
  Section::::Qualifying requirements for abortion providers.
   In its landmark 1973 case, "Roe v. Wade" where a woman challenged the Texas laws criminalizing abortion, the U.S. Supreme Court reached two important conclusions:
  
  BULLET::::- That state abortion laws are subject to the due process clause of the Fourteenth Amendment to the United States Constitution; and
   BULLET::::- "Planned Parenthood v. Danforth", 428 U.S. 52 (1976) is a United States Supreme Court case on abortion. The plaintiffs challenged the constitutionality of a Missouri statute regulating abortion. The Court upheld the right to have an abortion, declaring unconstitutional the statute's requirement of prior written consent from a parent (in the case of a minor) or a spouse (in the case of a married woman).
   BULLET::::- 2019 - The government of South Korea criminalized abortion in the 1953 Criminal Code in all circumstances. This law was later amended but not repealed. However, the Constitutional Court on 11 April 2019 ruled the abortion law unconstitutional and ordered the law's revision by the end of 2020.
   Because neither the factual underpinnings of Roe's central holding nor our understanding of it has changed (and because no other indication of weakened precedent has been shown), the Court could not pretend to be reexamining the prior law with any justification beyond a present doctrinal disposition to come out differently from the Court of 1973.
  
  The plurality further emphasized that the Court would lack legitimacy if it frequently changed its Constitutional decisions, stating,
   Abortion is legal in all U.S. states, and every state has at least one abortion clinic. Abortion is a controversial political issue, and regular attempts to restrict it occur in most states. One such case, originating in Texas, led to the Supreme Court case of "Whole Woman's Health v. Hellerstedt" (2016) in which several Texas restrictions were struck down.
   Other states have passed laws to maintain the legality of abortion if "Roe v. Wade" is overturned. Those states include California, Connecticut, Hawaii, Maine, Maryland, Nevada and Washington.
  
  The Mississippi Legislature has attempted to make abortion unfeasible without having to overturn "Roe v. Wade". The Mississippi law as of 2012 was being challenged in federal courts and was temporarily blocked.
   BULLET::::- United States: "Doe v. Bolton", 410 U.S. 179 (1973), was a decision of the United States Supreme Court overturning the abortion law of Georgia. The Supreme Court's decision was released on January 22, 1973, the same day as the decision in the better-known case of Roe v. Wade, 410 U.S. 113 (1973). Doe v. Bolton challenged Georgia's much more liberal abortion statute.
   BULLET::::- South Korea: The government of South Korea criminalized abortion in the 1953 Criminal Code in all circumstances. This South Korean abortion law was amended by the Maternal and Child Health Law of 1973, which permitted a physician to perform an abortion if the pregnant woman or her spouse suffered from certain hereditary or communicable diseases, if the pregnancy resulted from rape or incest, or if continuing the pregnancy would jeopardize the woman's health. Any physician who violated the law was punished by two years' imprisonment. Self-induced abortions were illegal, and punishable by a fine or imprisonment. The Constitutional Court on 11 April 2019 ruled the abortion law unconstitutional and ordered the law's revision by the end of 2020.
   BULLET::::- 1970 – Hawaii, New York, Alaska and Washington repealed their abortion laws. Specifically, Hawaii became the first state to legalize abortions on the request of the woman, New York repealed its 1830 law and allowed abortions up to the 24th week of pregnancy, and Washington held a referendum on legalizing early pregnancy abortions, becoming the first state to legalize abortion through a vote of the people.
  
  BULLET::::- 1970 - South Carolina and Virginia reformed their abortion laws based on the American Law Institute Model Penal Code.

   Before the U.S. Supreme Court decision "Roe v. Wade" decriminalized abortion nationwide in 1973, abortion was already legal in several states, but the decision imposed a uniform framework for state legislation on the subject. It established a minimal period during which abortion is legal (with more or fewer restrictions throughout the pregnancy). That basic framework, modified in "Planned Parenthood v. Casey" (1992), remains nominally in place, although the effective availability of abortion varies significantly from state to state, as many counties have no abortion providers. "Planned Parenthood v. Casey" held that a law cannot place legal restrictions imposing an undue burden for "the purpose or effect of placing a substantial obstacle in the path of a woman seeking an abortion of a nonviable fetus."
  
presuppositions: The US Supreme court ruling which deemed the banning of abortions unconstitutional should disallow states making abortion illegal. States are able to make abortion illegal.
corrections: Laws are guaranteed to be challenged in federal court, including the Roe v Wade decision making the banning of abortions unconstitutional, and such challenges can be successsful. Less about being able to and more about getting to challenge the supreme court.
