A judge dropped an arrest warrant Thursday for a University of Hawaii professor who refused to respond in court to English and spoke Hawaiian instead.

Samuel Kaleikoa Kaeo was in court Wednesday facing a trial for charges connected to his participation in a 2017 protest against the construction of a solar telescope on top of Haleakala, a volcano on Maui, Hawaii News Now reported .

When Judge Blaine Kobayashi asked Kaeo to confirm his identity, he repeatedly responded in Hawaiian instead of English.

Kobayashi said he couldn't understand Kaeo and issued a warrant for Kaeo's arrest, saying "the court is unable to get a definitive determination for the record that the defendant seated in court is Mr. Samuel Kaeo."

Kaeo, an associate professor of Hawaiian Studies at the University of Hawaii Maui College, said he has appeared before the judge before and complained that "it was about the fact that I was speaking Hawaiian that he didn't like."

Kobayashi recalled the bench warrant Thursday, the state Judiciary said in a statement. Judiciary spokesman Andrew Laurence declined to answer questions about the recall, including what prompted it.

Kaeo faces misdemeanor charges of disorderly conduct and obstructing a sidewalk. Kaeo, who also speaks English, requested a Hawaiian interpreter in the courtroom but prosecutors had objected, saying it was an unnecessary expense that would have caused delays.
