Appeals court smacks down judge for relying on Wikipedia

References to information at Wikipedia have shown up in various inappropriate places, from homework assignments to college term papers. But there's one place that it seems everyone can agree that it doesn't belong: the US court system. The US Court of Appeals for the 8th Circuit, ruling in an immigration case, has agreed with the Board of Immigration Appeals in finding that a reliance on information in Wikipedia is insufficient grounds for a ruling. Nevertheless, it sent the case back to the Board, requesting that it clarify its decision.

This relates, I believe, to our recent FastForward Radio discussion about whether judges or lawyers will one day be replaced by automated systems. Clearly, any such systems that come online will require more reliable data sources that Wikipedia.

Of course, we cite Wikipedia all the time at the Speculist, but then most of what we write doesn't subsequently become law.
