Supreme Court docket justices’ voting practices are pretty predictable. For example, most choices are unanimous. For the reason that longest serving justice on the Court docket, Justice Thomas, joined the Court docket in 1991, 42.65% of argued instances have returned unanimous votes. The Court docket additionally tends to reverse decrease court docket choices. The justices voted to reverse the decrease court docket choice in 65.58% of selections throughout the identical interval. The justices typically vote inside particular teams. These teams have been labeled conservative and liberal. Whereas there’s dispute inside the authorized neighborhood about the usage of political monikers for judges, the justices’ votes on points earlier than them typically parallel these of conventional politicians inside their respective voting blocs on related points. Inside these teams, justices are inclined to vote in the identical path as particular justices extra ceaselessly than others.
Whereas these patterns maintain in most situations, the justices often deviate from their conventional voting alignments. This raises the attention-grabbing query of why. What situations lead these frequent voting pairs to separate from one another? These explanations and together with a particular justice-pair evaluation are central to this text. Understanding these justices’ reasoning in these instances helps to separate out fine-grained understandings of the person justices by exhibiting the place we’d anticipate them to deviate from each other sooner or later.
When voting pairs are the main focus and votes are the unit of measurement, a number of convergent measures of voting habits assist generate attention-grabbing assumptions of voting pairs. The usually used political science measure for voting habits primarily based on voting pairs is the Martin and Quinn (MQ) Scores. The MQ Scores have been initially designed to clarify the justices’ voting habits between 1953 and 1999. Throughout that interval, the MQ mannequin predicted 74% of the justices’ votes appropriately which is a considerable enchancment over the 65.58% of votes predicted appropriately by at all times assuming the petitioner will at all times win. MQ Scores are dynamic within the sense that they fluctuate from time period to time period. They’ve been up to date by means of the tip of the earlier time period and the numbers look as follows:
From this, we will decide that probably the most dependable conservative justice pairing contains Justice Kavanaugh with Chief Justice Roberts.
Extra proof helps to solidify this level. Every time period, SCOTUSBlog tracks this information for all pairs of justice. This provides us different baselines for understanding the justices’ voting patterns. The voting alignment scores for every of the justice pairs listed above are as proven beneath:
Justices Kavanaugh and Roberts are the closest as they have been in the very same majorities for the 2021 Time period (this after all assumes concurrences are thought-about votes within the majority which is important for Roberts’s concurrence within the Dobbs case to be a vote in the identical path as Justice Kavanaugh’s the place Kavanaugh signed onto the Justice Alito’s majority opinion). On the low finish, each the Kavanaugh-Gorsuch pairings and the Roberts-Gorsuch pairings aligned 73% of the time.
The Variations
From when Kavanaugh joined the Court docket firstly of the 2018 time period by means of the tip of final time period, Chief Justice Roberts was within the majority 4 instances with out Justice Kavanaugh (5 instances if we embrace this time period’s Helix Power v. Hewitt) and Justice Kavanaugh was within the majority eight instances with out Chief Justice Roberts. Moreover, each justices have been in dissent collectively in 12 choices throughout this time. The 4 instances Chief Justice Roberts was within the majority with out Justice Kavanaugh previous to this time period have been in June Medical v. Russo, Dept. of Homeland Safety v. Regents of the College of California, Division of Commerce v. New York, and Bostock v. Clayton County. Roberts was the swing justice with the liberals in all however Bostock, which was additionally joined by Justice Gorsuch (the choice in Dept. of Commerce v. New York had numerous sections with completely different majority configurations however the Roberts was joined by Kagan, Sotomayor, Ginsburg, and Breyer in part 5 which describes how the district court docket was warranted in remanding the case again to the company).
All these instances have been on intently adopted by many and on the general public’s radar. They handled civil liberties together with abortion, transgender rights, immigration, and the census query regarding citizenship. This time period’s Helix Power was a decrease stakes case when trying on the disbursed results because it associated to govt exemptions from time beyond regulation pay.
The array of instances the place Justice Kavanaugh was within the majority with out Chief Justice Roberts is extra various. Though some regard Complete Girl’s Well being v. Jackson as a 9-0 or 8-1 choice, others regard the bulk holding as a 5-4 choice with Kavanaugh within the majority and Roberts in dissent with the extra liberal justices. The 5-4 majority determined that Texas officers couldn’t be held accountable for the enforcement of SB8 which allowed personal residents to file lawsuits for damages in opposition to anybody who “aids or abets” an abortion.
Apart from the plain stress between Justices Kavanaugh and Roberts over abortion associated points, the opposite instances the place Justice Kavanaugh was within the majority with out Justice Roberts included instances starting from felony issues, to free speech, and patent/expertise issues. These choices additionally primarily didn’t come right down to 5-4 splits and so there have been a mixture of the extra liberal and conservative justices within the majority.
The solely choice the place Kavanaugh was a swing justice together with 4 liberal justices was in Apple v. Pepper, the place Kavanaugh authored the bulk opinion permitting iPhone house owners that bought apps by means of Apple’s App Retailer to sue Apple beneath antitrust legal guidelines. The opposite 5-4 choice the place Justice Kavanaugh was within the majority with out Chief Justice Roberts was in Stokeling v. United States, which clarified the definition of “violent felony” beneath the Armed Profession Prison Act (ACCA) explaining {that a} enough diploma of pressure was one thing greater than the “slightest offensive touching.” Together with Justice Kavanaugh, the Stokeling majority consisted of Justices Thomas, Gorsuch, Breyer, and Alito.
The opposite non 6-3 majority with Justice Kavanaugh within the majority with out Roberts was within the 8-1 choice in Uzuegbunam v. Preczewski, which was additionally the solely time in Roberts’s historical past on the Court docket the place he was the sole dissenter. The holding in Uzuegbunam offered the plaintiff nominal damages for campus officers stopping Uzuegbunam from talking to college students about non secular beliefs on campus even when the campus coverage later modified to permit such speech actions. In dissent, Roberts wrote that the case turned moot after the change within the campus coverage.
Justice Gorsuch was the one justice to vote within the majority with Justice Kavanaugh in all the opposite 4 situations. The primary of those was Virginia Uranium v. Warren, the place Justice Gorsuch authored the bulk opinion joined by Kavanaugh, Thomas, Ginsburg, Sotomayor, and Kagan. The case handled federalism and particularly preemption the place the bulk held that the federal Atomic Power Act (AEA) doesn’t preempt a Virginia state-law ban on non-federal uranium mining.
The subsequent was Van Buren v. United States. The bulk opinion in that case was authored by Justice Barrett and together with Kavanaugh, the bulk included Justices Gorsuch, Sotomayor, Kagan, and Breyer.

The bulk held that some of these prohibitions in opposition to registration violated the free speech clause of the First Modification.
Some Ideas
No different justice pairs monitor as intently collectively as Justices Kavanaugh and Roberts throughout this era. Though Thomas and Alito are generally recognized because the farthest justices to the best on the present Court docket, since Kavanaugh joined the Court docket in 2018, Alito was within the majority 21 instances with out Thomas and Thomas was within the majority 15 instances with out Alito. Kavanaugh and Gorsuch voted collectively even much less ceaselessly as Kavanaugh was in 38 majorities with out Gorsuch and Gorsuch was in 11 majorities with out Kavanaugh.
Roberts and Kavanaugh are probably the most frequent justices within the Court docket’s majority. Since Kavanaugh joined the Court docket, each justices have been in dissent collectively on solely 12 events. Alito additionally dissented in all 12 situations, Thomas dissented in six, Barrett dissented in two (of the three whole the place she participated), whereas Gorsuch dissented in two, Breyer in a single, and each Sotomayor and Kagan in zero. 4 of those instances the place Gorsuch was within the majority with the liberals have been within the space of tribal regulation whereas 4 others have been within the space of felony regulation (Borden v. United States, United States v. Davis, Concepcion v. United States, and United States v. Haymond).
This time period up to now, Kavanaugh and Roberts have been within the two 5-4 majorities: Cruz v. Arizona and Bittner v. United States. Each majorities included various mixes of justices. Roberts was within the majority with out Kavanaugh within the time period’s different cut up choice: Helix Power v. Hewitt. If it is a signal of issues to return, then we may even see Roberts within the majority with out Kavanaugh extra ceaselessly and in much less high-profile instances. This, after all, will solely be doable if Roberts can persuade (or align with) a minimum of one different conservative justice to hitch such majorities alongside him. In Helix Power he had two, Gorsuch and Thomas, together with the three liberal justices to compose the six-justice majority.
