According to Cointelegraph, the U.S. Treasury Department argued that after removing Tornado Cash from the sanctions list on March 21, there is no need for a final court decision regarding lawsuits against Tornado Cash. The U.S. Treasury Department may wish to avoid further legal entanglements or explicit judicial decisions, especially considering that the federal appellate court has previously ruled that the Treasury's sanctions against Tornado Cash's smart contracts exceeded its statutory authority.
