(AP) — Opponents of a giant telescope planned for Mauna Kea on Hawaii Island are appealing the state land board’s approval of the project’s construction permit.

Richard Wurdeman, an attorney representing some of the opponents, filed a notice of appeal with the state Supreme Court on Monday.

The Board of Land and Natural Resources approved a construction permit in September for the Thirty Meter Telescope. Opponents of the $1.4 billion project say it will desecrate land sacred to some Native Hawaiians, while supporters say it will provide educational and economic opportunities.
