Amid questions from the Supreme Court about who has standing to sue, Solicitor General Elizabeth Prelogar said the federal government believes individual doctors still have broad "conscience protections" if they oppose abortion and decline to provide such access in specific instances.

Prelogar reaffirmed that later in the hearing when some justices returned to the topic but noted that the government believes there are exceptions under the law.

Preolgar previously argued that the government does not believe states have standing in this case to sue.

Solicitor General Elizabeth Prelogar is arguing the supposed harm cited by the anti-abortion alliance is "unduly speculative" and hypothetical.

"Their theories rest on a long chain of remote contingencies," she said. "Only an exceptionally small number of women suffer the kind of serious complications that could trigger any need for emergency treatment. It's speculative that any of those woman would seek care from the two specific doctors who asserted conscience injuries."

Prelogar also asserted that if there were any safety consequences to a drug, the FDA could take action itself to fix it.

Justice Clarence Thomas asked Solicitor General Elizabeth Prelogar if there is anyone who would have have a legal right to sue in this case -- which quickly emerged as the first major topic of the court's questioning of the federal government. The FDA has claimed the current plaintiffs do not have standing, with Prelogar suggesting at the hearing that their relationship to people who use mifepristone is too speculative and remote.

Prelogar said there may be an instance where a "competing drug manufacturer might sue and claim that FDA approval of a drug creates a competitive harm or injury or injury in that sense."

Chief Justice John Roberts asked if there is a number of adverse events or a number of patients who go to the emergency room in which the arguments would change. Facing such questions, Prelogar responded by reiterating her view that these possibilities appeared to be too theoretical and detached from specific decision-making and the history of patients who have used mifepristone.

Pelogar, in her opening statement, contended the anti-abortion plaintiffs have no standing and defended the FDA's approval of the drug.

She warned that the relief sought by the Alliance for Hippocratic Medicine would both "severely disrupt the federal system for developing and approving drugs" and "inflict grave harm on women across the nation."

Justice Ketanji Brown Jackson asked Erin Hawley, the attorney for Alliance Defending Freedom -- the group representing the plaintiffs -- if a nationwide reversal of the FDA's approval of mifepristone is needed and if the court can simply rule that doctors do not need to prescribe the pill if they have conscience objections.

"Do we have to entertain your argument that no one in the world can have this drug in order to protect your client?" the justice asked.

Hawley argued that given the "emergency nature," it is "impracticable" to not have a broader ban or block on access to the pill.

Justice Neil Gorsuch echoed Jackson's question and asked if it is enough for the court to rule on behalf of the plaintiffs not being required to prescribe the pill and why the court has to consider a universal injunction.
