Interest groups lobby the judiciary through three main tactics: filing amicus curiae briefs in pending cases, working to shape who gets appointed to the federal bench, and sponsoring strategic litigation designed to create favorable precedent. Most of this activity falls outside federal lobbying disclosure laws, which cover contacts with Congress and senior executive branch officials but not with judges.1Office of the Law Revision Counsel. 2 USC 1602 – Definitions That is what makes judicial lobbying quieter than its legislative counterpart, and often more consequential.
Filing Amicus Curiae Briefs
An amicus curiae brief, Latin for “friend of the court,” is a written argument submitted by someone who is not a party to the lawsuit. Organizations, trade associations, academics, and government bodies use these briefs to give courts a perspective the parties themselves might not raise: social science research, the economic consequences of a possible ruling, or an explanation of how a regulated industry actually operates.
At the Supreme Court, Rule 37 controls who can file. An outside group can submit a brief if every party consents or if the Court grants leave. The federal government and certain government officers have an automatic right to file without asking anyone.2Legal Information Institute. Supreme Court Rule 37 – Brief for an Amicus Curiae In the federal appeals courts, Rule 29 of the Federal Rules of Appellate Procedure works similarly: state and federal governments file freely, and everyone else needs party consent or court permission.3Office of the Law Revision Counsel. Federal Rules of Appellate Procedure Rule 29 – Brief of an Amicus Curiae
Who Paid for the Brief
Supreme Court rules force a measure of transparency about funding. Under Rule 37.6, the first footnote of an amicus brief must disclose whether a party’s counsel wrote any part of it and whether a party or anyone other than the filing organization gave money to prepare or submit it.2Legal Information Institute. Supreme Court Rule 37 – Brief for an Amicus Curiae Readers can therefore see when a corporation or wealthy donor has bankrolled a brief that appears to come from a neutral academic institute. The rules do not require nonprofits to publish their general donor lists, so the disclosure has real limits.
Do Judges Actually Read Them
The tactic works only if the justices pay attention, and they do. During the Supreme Court’s 2019–20 term, the justices cited amicus briefs in roughly 65 percent of argued cases that had amicus participation and a signed majority opinion. Briefs from the Solicitor General’s office are cited most often, reaching 63 percent that term, while private organization briefs are cited around 10 percent of the time. Over the preceding nine terms, the private-brief citation rate stayed between 5 and 12 percent, meaning dozens of outside arguments per term work their way into the Court’s reasoning.
Filing well is not cheap. Supreme Court briefs must meet strict printing specifications and pay a docket fee, and specialized appellate counsel add tens of thousands of dollars in attorney time.4Supreme Court of the United States. Memorandum to Those Intending to Prepare a Petition for a Writ of Certiorari in Booklet Format Well-funded groups treat the cost as routine. Smaller ones pool resources or sign onto briefs led by larger organizations.
Shaping Who Sits on the Bench
Because federal judges hold their seats for life, a single appointment can steer legal interpretation for decades. Interest groups spend heavily on the nomination and confirmation process, aimed at the White House and the Senate rather than the courts themselves.
Vetting Nominees Before and After Nomination
Serious groups start well before any name is announced. They research potential candidates by reading prior rulings, law review articles, speeches, and professional affiliations, and they keep shortlists of preferred picks that they share with the White House. Once a nomination is public, the campaigns move to media, grassroots mobilization, and direct outreach to senators on the Judiciary Committee.
Independent evaluation comes from the American Bar Association’s Standing Committee on the Federal Judiciary, which rates every nominee “Well Qualified,” “Qualified,” or “Not Qualified.” When the committee is split, the majority rating stands as the official view, with the minority position recorded alongside.5American Bar Association. Ratings of Article III and Article IV Judicial Nominees Groups on both sides cite these ratings in confirmation fights.
The Blue Slip
Home-state senators hold a quieter but potent lever. The Judiciary Committee sends each home-state senator a blue piece of paper asking whether they support or oppose a nominee from their state. By longstanding custom, the committee chair will not hold a hearing for a district court nominee who lacks a positive blue slip from both home-state senators.6U.S. Senator Chuck Grassley. Q&A: Blue Slips For interest groups, that means persuading one senator can stop a nomination in its tracks. The practice has been applied less consistently for circuit court nominees in recent years, but it still binds for district court seats.
What Tax-Exempt Groups Can and Cannot Do
Most groups running these campaigns are tax-exempt nonprofits, and the IRS draws lines around each type. Efforts to influence Senate confirmation of judicial nominees count as lobbying, not campaign intervention. That means 501(c)(3) charities can participate, but only if lobbying does not become a “substantial part” of their overall activities.7Internal Revenue Service. Attempts by Exempt Organizations to Influence Judicial Appointments The IRS decides where that line falls case by case, weighing both time and money spent on lobbying.8Internal Revenue Service. Measuring Lobbying: Substantial Part Test
501(c)(4) social welfare organizations operate under looser rules and can lobby without limit in service of their exempt purpose. In exchange, member dues used for lobbying are not deductible as business expenses, and the organization must either notify members of the nondeductible portion or pay a proxy tax on its lobbying spending.7Internal Revenue Service. Attempts by Exempt Organizations to Influence Judicial Appointments That structural difference is why the most aggressive confirmation campaigns tend to run through 501(c)(4) entities rather than traditional charities.
Sponsoring Strategic Litigation
The most direct way to change the law through the courts is to bring the right case at the right time. Strategic litigation means an interest group deliberately selects, funds, or orchestrates a lawsuit to establish a precedent that advances its broader agenda. The group may recruit plaintiffs, hire counsel, cover every litigation cost, and steer the case from a trial court through appeal, aiming for a ruling from a federal appellate court or the Supreme Court.
Test Cases in Practice
The classic example is the NAACP Legal Defense and Education Fund’s two-decade campaign against segregation in public education. Starting in the mid-1930s under Charles Hamilton Houston and later Thurgood Marshall, the organization pursued a deliberate sequence of cases against segregated law schools and graduate programs. Wins in Missouri ex rel. Gaines v. Canada (1938) and Sweatt v. Painter (1950) chipped away at “separate but equal” by forcing courts to compare the actual quality of segregated institutions. Each ruling narrowed the ground available to segregation’s defenders, building toward Brown v. Board of Education in 1954, where the Court held segregated public schools inherently unconstitutional.9United States Courts. History – Brown v. Board of Education Re-enactment
The same pattern shows up across the ideological spectrum. In District of Columbia v. Heller (2008), a senior fellow at the Cato Institute personally financed and orchestrated a Second Amendment challenge to Washington, D.C.’s handgun ban, interviewing dozens of potential plaintiffs before choosing six with diverse backgrounds to strengthen the case’s public appeal. The Supreme Court’s ruling recognized an individual right to keep handguns at home. Campaigns like this can take years and cost millions, and a favorable precedent reshapes the law nationwide.
Finding a Plaintiff With Standing
Interest groups cannot simply walk into court and demand a ruling. Article III limits federal courts to actual “cases or controversies,” so whoever brings the lawsuit must have standing: an actual or threatened injury, traceable to the defendant’s conduct, that a court ruling could fix or reduce.10Legal Information Institute. Standing Requirement: Overview
Plaintiff selection is where this gets strategic. A group that merely disagrees with a policy has no standing, but one whose members are directly harmed can sue on their behalf under associational standing. The Supreme Court’s three-part test from Hunt v. Washington State Apple Advertising Commission asks whether the members would have standing individually, whether the suit’s goals relate to the organization’s purpose, and whether the claims can proceed without each member participating.11Library of Congress. Hunt v. Washington State Apple Advertising Commission, 432 U.S. 333 (1977) Poorly planned test cases collapse at this stage, which is why experienced litigators spend so much effort finding the right plaintiff before filing anything.
Why Most of This Isn’t Reportable Lobbying
Federal law requires paid lobbyists to register and file disclosures when they contact members of Congress or senior executive branch officials. The Lobbying Disclosure Act defines a “lobbying contact” as communication with a “covered executive branch official” or “covered legislative branch official.” Judges appear nowhere in either definition.1Office of the Law Revision Counsel. 2 USC 1602 – Definitions Filing an amicus brief, funding a test case, or running a public campaign around a pending ruling can shape the law without triggering any lobbying registration.
Judicial nominations are the exception. Senate confirmation votes are cast by senators, who are covered legislative branch officials, so paid efforts to influence a confirmation count as reportable lobbying.1Office of the Law Revision Counsel. 2 USC 1602 – Definitions An organization running television ads urging senators to confirm or reject a nominee is lobbying. The same organization filing an amicus brief at the Supreme Court is not. That gap is why briefs and strategic litigation remain the less visible tools in the interest group playbook, and often the more powerful ones.
