Fix the Court sent a letter today to Scott Harris, the clerk of Supreme Court, urging the creation of a more thorough conflict-check system to ensure that the Justice Breyer stock oversight does not happen again.

Last week Breyer heard a case in which one of the parties was a publicly traded company whose stock he owned, which should have triggered a recusal. Once Breyer realized the mistake he sold his shares.

Fix the Court is calling on the justices who own common stock to place their securities in blind trusts for the duration of their high court tenure and is asking that the justices share their internal conflicts lists with their colleagues to help mitigate the potential for slip-ups like last week’s.
