Established in 1977, Atlantic Legal Foundation, also known as ALF, is a 501(c)(3) nonprofit, nonpartisan public interest law firm that litigates individual liberty, deregulation, free enterprise, and private property rights.

The Foundation has filed briefs in cases concerning free speech, equal protection, due process, federalism, separation of powers, property rights, and international law.

[19] ALF argued that DaimlerChrysler AG could not be held liable for the conduct of its Argentinian subsidiary and because a German Corporation had more interest in the suit's resolution.

Atlantic Legal's “sound science” program advocates for the admissibility of medical testimony in toxic tort, product liability, and other types of litigation.

This program aligns with their resolve to "redress[] the bias against business which manifests itself in favor of narrow ‘consumer’ or ‘environmental’ concerns.”[1] Atlantic Legal challenges the admissibility of "junk science" in the courtroom.

[20] The Foundation claims it has "successfully challenged bogus theories of medical causation" in toxic tort cases involving asbestos and other hazardous substances.

[27] A major part of this effort is publishing a series of state-specific union-busting guides titled "Leveling the Playing Field", which inform charter school leaders how to combat labor union organizing campaigns.

[35] While individual donors and non-profit organizations comprise the majority of ALF's funding, the Foundation has also received contributions from corporations such as the oil company ExxonMobil.
