The 2023 Supreme Court Term runs from Oct 2nd, 2023 - Oct 7th, 2024.

We are counting unanimous decisions as ones where justices join the court’s opinion (regardless if any justices file concurrences, or only join in part). Going off the wikipedia article, we are counting rows which are entirely Blue+Green or Red+Purple, ignoring asterisks and dashes.

Examples of what would be counted as unanimous includes:

• Bartenwerfer v. Buckley [unanimous decision with Sotomayor and Jackson joining a concurrence]

• Delaware v. Pennsylvania [unanimous decision on Parts I, II, III, and IV-A]

• Southwest Airlines Co. v. Saxon [unanimous decision with Barrett taking no part in the case]

Past years’ data:

• 2022 [48%, 28/58]

• 2021 [30%, 20/66]

• 2020 [41%, 28/68]
