We have the first decision. It is by Justice Jackson and it is unanimous.
M & K Employee Solutions, Inc. v. Trustees of IAM Nat. Pension

This is a case about the interpretation of ERISA and in particular how to calculate unfunded vested benefits .
Just the type of case to keep Jackson busy without her interfering in a case of major national consequence. IMHO
