PANews reported on April 30 that according to Decrypt, Coinbase and other parties submitted a friend of the court brief, urging the US Supreme Court to accept the "Harper v. O'Donnell" case and re-examine the applicability of the third-party disclosure principle in the digital age. The case originated from the IRS's request for Coinbase to provide transaction data of more than 14,000 users through a "John Doe subpoena". Coinbase pointed out that this practice constitutes "financial shackles" monitoring of blockchain users, infringing on their privacy rights guaranteed by the Fourth Amendment of the Constitution. Whether the court will accept the case is expected to be decided this year.
