Whether States can independently interpret federal laws regarding Variable Separation Incentive (VSI) as a retirement benefit, and whether Massachusetts violated due process by altering a 20-year-old final judgment

ONE A dozen States' Appellate Courts have issued opinions holding that Variable Separation Incentive (VSI) is a retirement benefit/pension. Subsequently, Massachusetts courts ruled VSI is not a retirement benefit/pension. Are States free to interpret federal laws however each prefers, or is Massachusetts incorrect? (Or are the dozen other states?) QUESTION TWO Massachusetts altered a 1999 Judgment that had been final for 20 years. Does this violate U.S. Constitution Fourteenth Amendment Due Process? Petition for Writ of Certiorari 1 PARTIES All parties appear in the caption on the cover. PROCEEDINGS BELOW In Norfolk County, Mass. Family Court's Dkt. No. 98D0300, Ron Waterman, Plaintiff vs. Robyn Waterman, Defendant, Judgment of Divorce was final in 1999.
