Final answer:
The U.S. Supreme Court will not agree to hear a tax case if it involves a purely procedural matter without substantive tax implications.
Step-by-step explanation:
The U.S. Supreme Court may agree to hear a tax case for various reasons, but there is one reason that is not sufficient. That reason is option d) The case involves a purely procedural matter without substantive tax implications.
When the Supreme Court decides which cases it will hear, it looks for conflicts on an issue between or among the lower courts. It also considers cases that have special urgency or cases that involve conflicting decisions among different courts of appeals or state and federal court decisions.
However, a tax case that involves only a procedural matter without substantive tax implications is not enough reason for the Supreme Court to agree to hear it.
