More on how this was screened

The later opinions reported Fox Film's overruling rather than independently acting on Long.

Every treatment on this page is written from the citing opinion itself, with a verbatim quote, never copied from a commercial citator. A citation flagged by our screen but not shown here was read and found not to weaken this case.

6 later cases cite Long v. Rockwood; 6 of those citations sat close to treatment language and were flagged for reading, and all of them have been read. Citations that did not sit near treatment language were not flagged and were not read one by one, so a court that weakened this case without using any of that language would not appear here.

    Fox Film Corp. v. Doyal · Supreme Court of the United States · filed

    The affirmance of the judgment in the instant case cannot be reconciled with the decision in Long v. Rockwood, 277 U. S. 142, upon which appellant relies, and in view of the conclusions now reached upon a re-examination of the question, that case is definitely overruled.
