(AP) — A Native Hawaiian fisherman is asking an environmental court to stop Hawaii officials from issuing commercial fishing licenses to those who aren’t legally admitted into the United States.

Malama Chun, a Maui resident who fishes as a cultural practice, filed an appeal on July 27 of a state Board of Land and Natural Resources decision denying his petition. Chun filed his petition in April in response to an Associated Press investigation that found hundreds of foreign fishermen confined to boats and some living in subpar conditions. Hawaii grants the foreign fishermen licenses to fish, but they aren’t allowed to enter the country.

The board, which regulates fishing licenses, denied the petition last month without a hearing. It said Chun didn’t show how not issuing the licenses would address his concerns about overfishing and cultural practices. His attorney, Lance Collins, said Tuesday that because the board made a decision without holding a hearing or conducting any fact-finding, the board must take all stated facts as true.
