The ACLU and several other advocacy groups filed a lawsuit against the Trump Administration on Tuesday over a new policy that allows healthcare workers to deny patients information and treatment based on personal religious or moral beliefs.

The underlying issues in play draw on the ongoing national debate over whether “religious freedom” allows a person to avoid what would otherwise be a legal obligation on the basis that following the law would offend their religious beliefs.

In a statement on its website, the ACLU stated that it took up this fight because Trump’s new rule is seriously dangerous in that, “It forces health centers that receive federal funds to employ individuals who refuse to perform essential job functions, without any regard for the wellbeing of their patients or public safety.” The rule, officially titled “Protecting Statutory Conscience Rights in Health Care,” was first announced by President Donald Trump in a Rose Garden press conference last May, on the National Day of Prayer. It is set to take effect July 22.
