币界网报道：The U.S. Supreme Court declined to hear a case challenging the IRS's authority to collect customer data from cryptocurrency exchanges without a warrant, dealing a blow to privacy advocates. Coinbase had warned that the government's broad data requests could set a dangerous precedent for financial surveillance in the crypto sector. The case stemmed from a 2016 IRS summons demanding Coinbase provide records for over 14,000 users suspected of tax evasion. While lower courts sided with the IRS, privacy groups argued the demands violated Fourth Amendment protections against unreasonable searches. The Supreme Court's refusal to review the case leaves intact the IRS's ability to access crypto transaction data through administrative summonses rather than court-ordered warrants.
