When the state deemed Leighton Pang Kee ineligible for one of the most valuable benefits available to Native Hawaiians — land at almost no cost — because he couldn’t show that he was at least 50 percent Hawaiian, he sued. “A Hawaiian is a Hawaiian is a Hawaiian,” said Michelle Kauhane, president and CEO of the Council for Native Hawaiian Advancement. The testing to prove Hawaiian ancestry is more like a paternity test, said Camille Kalama, an attorney for the Native Hawaiian Legal Corp., which sued on Pang Kee’s behalf.
