Here is REQUEST (not ruling) from the Supreme Court word by word: "The application for injunctive relief, presented to Justice Kagan and by her referred to the Court, is treated as a petition for a writ of certiorari before judgment, and the petition is granted. The September 2 order of the United States District Court for the Central District of California is vacated, and the case is remanded to the United States Court of Appeals for the Ninth Circuit with instructions to remand to the District Court for further consideration in light of Roman Catholic Diocese of Brooklyn v. Cuomo, 592 U. S. ___ (2020).
So, let's break it down

The appeal is treated as " a petition for a writ of certiorari before judgment, and the petition is granted". So what is the definition of "writ of certiorari"? A writ of certiorari mean: "A writ of certiorari is a decision by the U.S. Supreme Court to hear an appeal from a lower court. The word certiorari comes from a Latin word meaning to be more fully informed. And the act of “granting certiorari” means the Supreme Court agrees to hear a case. Then the Supreme Court order the Unite State District Court that the case is vacated and the case is remanded to United States Appeal Court of Ninth Circuit. Now let's see what Remand means: "Remand means to order back, such as a to send back (a case) to another court or agency for further action."
Now that decision was 9-0 by all SCOTUS justices.
When a plaintiff lose a case in a Federal court and appropriate federal appeal court (in this case 9th circuit) and the Supreme Court and SCOTUS issue a writ of certiorari to the appeal court of jurisdiction of were the Federal suit was filed, Then the appellate court will decide whether to grant or deny certiorari. If Certiorari is issued, designated as "cert. granted," when the case presents an issue that is appropriate for resolution by the court and it is in the public interest to do so, such as when the issue has been decided differently by a variety of lower courts, thereby creating confusion and necessitating a uniform interpretation of the law. Certiorari is denied when the appellate court decides that the case does not present an appropriate matter for its consideration. In the practice of the Supreme Court, if a petition has been granted certiorari as a result of a mistake, such as where the petitioner misrepresents the case or the case has become moot, the Court will dismiss the petition as "having been improvidently granted," which has the same effect as an initial denial of the petition. And practically speaking, this rarely occurs.
In nutshell the 9-0 decision was keeping the bucket down the road for NOW.
