He wore a headdress to the Supreme Court. They wouldn't let him because it might obstruct someone's view

Chairman JoDe Goudy arrived to a U.S. Supreme Court hearing in full regalia.

“The court is not to be subject to outside influence," said a security guard in a video posted by Goudy to Facebook. "The headdress itself will not be allowed inside the courtroom.”

The guard told Goudy there were “decorum issues in the courtroom” and his headdress could obstruct the view for others. Chairman Goudy called the experience “dehumanizing.”

“I wouldn’t say it was an outright show of disrespect,” Goudy said. “I think there is probably some misinterpretation and misunderstanding with regard to what our traditional attire and regalia means to us, what it would mean to a person who wears a headdress to essentially ask them to remove it."

The U.S. Supreme Court heard arguments Tuesday in a five-year-old case that questions the rights outlined in an 1855 treaty between the United States and Washington’s Yakama Nation.

Yakama Tribal Chairman JoDe Goudy says his tribe agreed to give up a swath of land larger than the state of Maryland when they signed the treaty.
