LONDON — The Dutch Supreme Court on Friday upheld a decision that the Netherlands was partly responsible for the deaths of 350 Muslim men during the 1995 Srebrenica massacre, but it slashed the level of liability for the Dutch government that was established in an earlier ruling.

An estimated 8,000 Muslim men and boys were killed by Bosnian Serb paramilitaries after the storming of Srebrenica — a then mostly Muslim town in what is now the semiautonomous Serb region of Bosnia and Herzegovina — under the noses of Dutch peacekeeping troops assigned by the United Nations to protect it. The massacre was the worst in Europe since World War II.

In a summary of the judgment posted online, the court said it accepted the state’s liability for damages experienced by the surviving relatives of 350 men who were ordered by Dutch troops to leave the peacekeepers’ compound two days after the town was taken, and said they could claim compensation.

But it limited that liability to 10 percent, a significant reduction from a 2017 court ruling by a Dutch court that established the state’s responsibility at 30 percent, meaning that the amount of damages that can be claimed from the Dutch government was similarly diminished.
