The job of the Supreme Court is to make sure that Congress and the President follow the rules. But what happens when justices of America’s highest court step out of line?
Take Chief Justice John Roberts: In October, Roberts took part in an Oct. 5 disposition regarding an environmental cleanup case in which Texas Instruments (TXN) was one of the companies seeking review, according to a report in Bloomberg.
Financial disclosure forms from 2014, however, show that Roberts or a close family member owned between $100,000 and $250,000 in Texas Instruments stock. Ruling on a case where there is such a conflict of interest is against the law, according to the report. In an email to Bloomberg, Kathy Arberg, the Supreme Court’s spokeswoman, said attributed the mistake to “human error.”
The oversight is being used by critics of the Supreme Court’s ethics rules as evidence that the institution is in need of reform. Gabe Roth, executive director of Fix the Court told Bloomberg, “Chief Justice Roberts’s oversight … demonstrates that the Supreme Court’s current system of self-checking for conflicts isn’t working.”
Roth, a former journalist, launched his group last year to increase transparency in the Supreme Court and publicize conflicts of interest that plague the highest constitutional authority. In an op-ed in the Los Angeles Times published last year, Roth wrote:
Justice Samuel A. Alito‘s sister is a high-powered labor attorney who represents management in disputes with workers. Justice Elena Kagan‘s brother, a teacher at an elite public school in New York, has protested the school’s admissions process because of low minority enrollment. And Justice Stephen G. Breyer‘s son co-founded a tech company that broadcasts civil court proceedings.
Does having relatives involved in labor disputes, affirmative action battles and cameras in courtrooms affect how Supreme Court justices decide cases and manage their institution? They say no, and we’re supposed to take them at their word. But is “trust us” really good enough for the nation’s highest court?
A confluence of recent events has made the Supreme Court the most powerful, least accountable public institution in the country. It is time to make the justices more accountable to the American people.
