Problem: The presence of pain in an animal cannot be known for certain, but it can be inferred through physical and behavioral reactions. Specialists currently believe that all vertebrates can feel pain, and that certain invertebrates, like the octopus, might too. As for other animals, plants, or other entities, their ability to feel physical pain is at present a question beyond scientific reach, since no mechanism is known by which they could have such a feeling. In particular, there are no known nociceptors in groups such as plants, fungi, and most insects, except for instance in fruit flies.

Problem: It was announced on 19 March 2015 that self-governance for the island would be revoked by the Commonwealth and replaced by a local council with the state of New South Wales providing services to the island. A reason given was that the island had never gained self-sufficiency and was being heavily subsidised by the Commonwealth, by $12.5 million in 2015 alone. It meant that residents would have to start paying Australian income tax, but they would also be covered by Australian welfare schemes such as Centrelink and Medicare.

Problem: Thirty-nine Native American tribal governments are based in Oklahoma, each holding limited powers within designated areas. While Indian reservations typical in most of the United States are not present in Oklahoma, tribal governments hold land granted during the Indian Territory era, but with limited jurisdiction and no control over state governing bodies such as municipalities and counties. Tribal governments are recognized by the United States as quasi-sovereign entities with executive, judicial, and legislative powers over tribal members and functions, but are subject to the authority of the United States Congress to revoke or withhold certain powers. The tribal governments are required to submit a constitution and any subsequent amendments to the United States Congress for approval.
Who can overrule the tribal governments?

the United States Congress
