In its first opinion on escheatment in three decades—and Associate Justice Ketanji Brown Jackson’s first majority opinion—the U.S. Supreme Court ruled Tuesday Delaware isn’t entitled to unclaimed checks from MoneyGram Payment Systems Inc. that were purchased in other states.

The decision resolves a dispute that dates back to 2017, finding the MoneyGram checks are similar enough to money orders to be subjected to the Federal Disposition Act, requiring Delaware to redistribute at least $150 million to other states.
