What does HA mean in US GOVERNMENT

Examples of higher authorities include national governments and international bodies like the United Nations, regional authorities like local councils and state legislatures, religious institutions such as the Catholic Church, and judicial systems like the Supreme Court.

It depends on what kind of higher authority you are referring to. National governments are made up of elected officials who represent their constituencies in government affairs. International bodies have representatives from different countries. Religious institutions have leaders such as priests or bishops who lead the church's operations and teachings. Judicial systems are made up of judges appointed by other branches of government or voted into office by the people.

Higher authorities possess ultimate authority within their domain or area of jurisdiction. They wield the power to create laws, regulations and policies that must be respected and obeyed by those under their control or within their scope. The scope may vary depending on its source - for example, international bodies have generally wider reach compared to local councils.

Depending on the type and nature of higher authority involved, there may be specific procedures for appealing against its decisions. For instance in most democracies governed via representative democracy (through elected officials), one can appeal against particular decisions made by electing new representatives at upcoming elections who support a different agenda than that which led to those decisions originally being taken.

Yes this is possible depending on how well established legal rights exist in that country/ region — e.g., in certain cases individuals may challenge interpretations made by governmental bodies through use of judicial review mechanisms available within that country/region.
