full_context: Document 1: Atlantic Sounding Co. v. Townsend: Atlantic Sounding Co. v. Townsend, 557 U.S. 404 (2009) , was a decision by the Supreme Court of the United States holding that a seaman may recover punitive damages from his employer for failure to pay maintenance and cure. "Townsend" reversed a line of cases, starting with "Guevara v. Maritime Overseas Corp." in the United States Court of Appeals for the Fifth Circuit (New Orleans), that restricted damages in maritime personal injury cases only to "pecuniary" damages. Consequently, a seaman can now recover both attorney's fees and punitive damages for the willful and wanton refusal of a shipowner to provide medical care to a seaman injured on the job. The Court's 5-4 opinion was delivered by Justice Clarence Thomas.

Document 6: Peter Rost (doctor): Peter Rost, M.D. is a former drug marketing executive and is most known for taking public stances critical of the pharmaceutical industry as an "insider" and whistleblower. He sued his last two pharmaceutical employers, Wyeth and Pfizer, the latter of which fired him in 2005. At Wyeth, he uncovered tax evasion practices, and after informing senior company executives, was transferred from Sweden to a post in New Jersey. Rost sued the company, saying that the transfer was a retaliatory demotion, though the company said it was a promotion. Rost settled with Wyeth for an undisclosed amount in 2003. At Pfizer, Rost filed a "qui tam" suit disclosing off-label marketing of Genotropin at Pharmacia prior to its purchase by Pfizer. The U.S. Department of Justice declined to join in Rost's suit as the marketing violations had already been disclosed to the Department by Pfizer. Rost was eventually fired by Pfizer, and sued for wrongful dismissal, but this lawsuit was summarily dismissed by the court based on evidence that Pfizer had decided to fire Rost prior to discovery of his whistleblowing activities. Since then, Rost has worked outside the pharmaceutical industry, as a public speaker, blogger, writer, and litigation consultant.
Document 7: Commissioner v. Banks: Commissioner v. Banks, 543 U.S. 426 (2005), together with Commissioner v. Banaitis, was a case decided before the Supreme Court of the United States, dealing with the issue of whether the portion of a money judgment or settlement paid to a taxpayer's attorney under a contingent-fee agreement is income to the taxpayer for federal income tax purposes. The Supreme Court held when a taxpayer's recovery constitutes income, the taxpayer's income includes the portion of the recovery paid to the attorney as a contingent fee. Employment cases are an exception to this Supreme Court ruling because of the Civil Rights Tax Relief in the American Jobs Creation Act of 2004. The Civil Rights Tax Relief amended Internal Revenue Service § 62(a) to permit taxpayers to subtract attorney’s fees from gross income in arriving at adjusted gross income.

Gorsuch, age 49, is the youngest sitting Supreme Court justice since Clarence Thomas.

Article II of the U.S. Constitution requires the president to nominate justices to the Supreme Court, subject to the "advice and consent" of the United States Senate. President Barack Obama, a Democrat, nominated Merrick Garland to fill the vacancy. U.S. Senate majority leader Mitch McConnell, a Republican, arguing that the presidential election cycle having already commenced made the appointment of the next justice a political issue to be decided by voters, refused to bring the Garland nomination to the Senate floor for a vote. McConnell's action held the Supreme Court vacancy open through the end of President Obama's tenure.
