In what cases does the Missouri Supreme Court have original jurisdiction?

The Missouri Supreme Court's original jurisdiction is specifically defined in the Missouri Constitution. It holds original jurisdiction in a limited set of cases, notably including habeas corpus cases and challenges to the constitutionality of state laws. This means that the Supreme Court can hear these cases directly, without them first going through lower courts. The ability to handle habeas corpus cases is crucial because it allows the court to address issues of unlawful detention, ensuring that personal freedoms are upheld.

Other types of cases mentioned do not fall within the original jurisdiction of the Missouri Supreme Court. For instance, while state tax disputes and administrative agency appeals are significant legal matters, they typically start in lower courts and can be appealed to the Supreme Court later. Therefore, option B accurately identifies the specific instances in which the Missouri Supreme Court has the authority to hear cases from the outset.
