It’s not a new precedent and not national law. The states decide. The following is from a NYT article earlier this year.
In the 1977 decision, Abood v. Detroit Board of Education, the Supreme Courtmade a distinction between two kinds of compelled payments. Forcing nonmembers to pay for a union’s political activities violated the First Amendment, the court said. But it was constitutional, the court added, to require nonmembers to help pay for the union’s collective bargaining efforts to prevent freeloading and ensure “labor peace.”
The Abood v. Detroit Board of Education was effective only upon the parties in involved, not all parties everywhere as is commonly supposed and followed. (AND a federal question case is legitimately effective ONLY IF the opinion and decision was reasonably based on the Constitution as written and originally understood and intended.)
All governments, state and federal, follow this constitutional perversion as easily seen with cases like Roe v. Wade. The feds and the states took Roe v. Wade as national federal law, a wrong conclusion on two counts. One, the decision was not constitutional, and two, even if the decision was constitutional, it was effective only upon the parties of the case.
