The justices of the US Supreme Court. [/caption] The three U.S. Supreme Court justices who own significant stock holdings have continued to sell some but not all of their shares, according to 2017 financial disclosure forms made public on Thursday. Justice Samuel Alito Jr., whose stock holdings increased because of an inheritance several years ago, reported more than 20 partial or full stock sales in 2017, according to his form. Mutual funds, bank accounts and Treasury and municipal bonds are not included. Likewise, Justice Stephen Breyer shed some or all of seven company stocks, roughly half of what he had in 2016. Chief Justice John Roberts Jr. sold holdings in three stocks, including Nokia shares valued at $15,000 or less. But he retained between $250,001 and $500,000 in Time Warner stock, and a similarly valued number of shares in Sirius XM, which figured in a recusal earlier this week. He recused in a challenge of Major League Baseball's antitrust exemption. Liberty Media Corporation. has 71 percent ownership in SiriusXM, and 100 percent ownership of the Atlanta Braves. Other stock sales reported in the forms also help explain the justices' recusal behavior in cases before the court. Alito's financial disclosure form, for example, confirmed he sold his holdings in Schlumberger Limited, valued at less than $15,000, in December. He recused himself earlier last year in the patent infringement case WesternGeco v. ION Geophysical, likely because WesternGeco is an indirectly, wholly owned subsidiary of Schlumberger. The court announced in January that Alito was "unrecused" in the case—the result of his stock sale a month earlier. The case is still pending decision. The transparency advocate Fix the Court has urged justices to sell all stock holdings and put their money into blind trusts to avoid conflicts and recusals. According to the organization's analysis of the forms today, the three justices continue to retain these stock holdings as of the end of 2017: —Roberts: Lam Research, Sirius XM, Texas Instruments, Thermo Fisher Scientific, TIME Inc., Time-Warner, Charter Communications —Breyer: ADP, Applied Analysis, Cintas, Fastenal, Lowe’s, Paccar, Pearson, Sysco, UTC —Alito: 3M, Abbott Labs, Abbvie, AES, Becton Dickinson, BHP Biliton, Black Hills, Boeing, Caterpillar, CDK Global, ConocoPhillips, DowDuPont, Fortis, Jacobs Engineering, Johnson & Johnson, L’Occitane, Merck, MolsonCoors, Mondelez, OGE Energy, Oracle, Parker Hannifin, Phillips 66, PNC, Procter & Gamble, Sealed Air, TJ Maxx, UTC Here are some other tidbits from the newly released financial disclosure forms:>>> Book royalties continue to supplement justices' salaries. Justice Neil Gorsuch reported receiving $9,020 in royalties from Princeton University Press, which published his book The Future of Assisted Suicide and Euthanasia. It was published in 2009, but public interest in Gorsuch around his confirmation in 2017 likely boosted sales. >>> Justice Sonia Sotomayor received advance royalties from Penguin Random House of $117,500, for two books she is writing. >>> Justice Samuel Alito Jr., like other justices, earned outside money through law school teaching engagements. Duke University School of Law paid him $15,000 for four days of teaching in January, 2017. He also taught in Rome, Italy for Loyola University of Chicago Law School for 10 days, earning $12,765. >>> Justice Ruth Bader Ginsburg received $25,000 as the Rathbun Visiting Fellow at Stanford University on February 6 and 7, 2017. It was one of 13 reimbursed trips Ginsburg reported. Justice Elena Kagan was paid $17,500 for teaching at Harvard Law School where she previously served as dean. >>> Justice Anthony Kennedy reported few assets. His only non-investment income continues to come from his adjunct teaching position at McGeorge School of Law: $12,500. He teaches every summer at the law school's program in Salzburg, Austria, and is heading there on July 1. >>> Justice Clarence Thomas brought in teaching income of $27,765 from stints at three law schools: George Mason University Antonin Scalia Law School, Creighton Law School and George Washington University School of Law.
