Cryptocurrency think tank Coin Center has won approval from the U.S. Court of Appeals to reopen a lawsuit against the Treasury Department and the Internal Revenue Service. In 2022, Coin Center sued them over a controversial amendment to the U.S. tax code that requires people to disclose certain crypto transactions to the IRS, as well as the personal details of participants in those transactions. Coin Center argued that the amendment violates the U.S. Constitution and is evidence of "overbearing surveillance" of crypto users. (CoinDesk)
