Constitutional laws are laws that are adopted by whole nations, and are the highest power in the legal system. All other laws--at the state and local levels--must agree with and obey the Constitutional laws. Amendments are accepted into the constitution and become law.

Statutory laws are enacted by Congress, whether at the state or federal level. Ordinances fall under this category. Ordinances are laws enacted by town/city governments under the authority of state congress.
These laws are created by all levels of government--federal, state, and local. These laws function as regulators of laws already in place. Administrative laws carry out existent laws and are regulated by the executive of whatever level of government they originate in (president, governor, mayor).

Case laws are made from decisions at the federal and state courts. These laws are based on precedents set at lower courts. A good example of a Case Law is the legalization of same-sex marriage.
