The Thirty Meter Telescope project on Mauna Kea has cleared its final legal hurdle, it’s hoped. The state Supreme Court, which last month allowed a construction permit for TMT to proceed, last week denied a motion to reconsider its ruling.

Going forward, the project’s proponents and opponents will need to work through their differences peacefully and within the law. The long fight over TMT already has produced important, culturally sensitive reforms to Mauna Kea summit management. That, and the tremendous scientific value of TMT, make for a reasonable compromise.

Good news, bad news for Marriott

Staycationers: You may want to double-check your hotel records. Marriott International said on Friday that hackers have accessed its Starwood Hotels’ reservation database since 2014, potentially exposing personal information on about 500 million guests. Twelve properties in Hawaii are affected.

This news about what may be among the largest data breaches on record capped a bad news-good news week for Marriott Hawaii. On the good news side, a 51-day strike ended with some 2,700 hotel workers getting pay and benefit hikes. They’re now back to work at Marriott-­managed Sheraton Waikiki, Royal Hawaiian Hotel, Westin Moana Surfrider, Sheraton Princess Kaiulani and Sheraton Maui.
