The text of the remaining citing opinion could not be reliably retrieved.

The treatments below are confirmed; unread citations could still change the overall status.
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.

18,486 later cases cite Erie Railroad v. Tompkins; 1,073 of those citations sat close to treatment language and were flagged for reading; the progress bar above tracks how many have been read so far. 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.

Treatments

Criticized

  • The district court criticized the effect of Erie on unfair competition law, saying it pushed federal courts toward old state decisions.

    Continental Casualty Company v. Beardsley · S.D.N.Y. · filed

    Erie Ry. Co. v. Tompkins, 1938, 304 U.S. 64, 58 S.Ct. 817, 82 L.Ed. 1188. The law of unfair competition has largely been developed in the federal courts, and most unfair competition cases are still brought there. Since Erie, however, many of the federal courts have felt compelled to ignore their own precedents and rely instead on old state decisions. The result, as can be seen from reading the federal cases cited in support of Illinois law, notes 55-57, infra, is an endless exegesis on a perhaps antiquated decision instead of a dynamic approach to decisional law.
