Braswell v. United States is a significant Supreme Court case from 1988 that addressed the issue of self-incrimination in relation to the Fifth Amendment. The case involved a business owner, Braswell, who was compelled to produce corporate records that could incriminate him personally. The Supreme Court ruled that individuals cannot refuse to comply with a subpoena for business records simply because they may incriminate them, emphasizing the distinction between personal and corporate rights against self-incrimination.
