Definition of F.SUPP. 2D

F.Supp. 2d stands for Federal Supplement, Second Series.

This term refers to a specific collection of published legal opinions from federal trial courts in the United States. Specifically, it compiles decisions from the U.S. District Courts (the primary federal trial courts) and the U.S. Court of International Trade. The "Second Series" indicates that these are cases published from 1997 to the present day, distinguishing them from earlier volumes of the Federal Supplement.

Here are some examples of how this term applies:

  • Example 1: Researching a Patent Dispute

    Imagine a legal team representing a tech company involved in a patent infringement lawsuit. They need to find a previous ruling from a federal district court in California concerning a similar technology. If they locate a relevant case decided in 2005, its citation would likely include "F.Supp. 2d," indicating that the full text of that decision can be found in the Federal Supplement, Second Series, providing them with valuable precedent for their current case.

  • Example 2: Citing a Landmark Environmental Ruling

    A law student is writing a paper on the evolution of environmental law in federal courts. They want to reference a significant decision made by a U.S. District Court in 2010 that set a new standard for corporate accountability in pollution cases. When citing this case in their paper, they would use its official citation, which would include "F.Supp. 2d," directing readers to the specific volume and page number within this series where the full opinion is published.

  • Example 3: Investigating a Trade Dispute

    A journalist is researching a story about a recent tariff dispute between the U.S. and another country, which was decided by the U.S. Court of International Trade in 2018. To understand the court's reasoning and the legal basis for its decision, the journalist would look up the case. The official published opinion of that court, being from 2018, would be found in the "F.Supp. 2d" series, allowing the journalist to access the precise legal language and findings.
