The 500 case summaries below are a representative sample of the 749 cases in which the ACLU was involved at the US Supreme Court level (overwhelmingly as amicus filers), from their first case decided on June 8, 1925 through Dec. 31, 1999.

These "layman" summaries are targeted primarily for non-lawyers, so the case descriptions and related information are in straightforward easily understood language.

Some of the summaries and case descriptions presented were written by law students and researchers, and therefore may be missing some important legal nuances or contain erroneous data. However, in the majority of the cases, in order to avoid rewriting or reinterpreting the opinion of the Court, we used verbatim the relevant portions of the case summaries and opinions as published by the Supreme Court. We are in discussions to have all 749 case summaries published in print form.
