In the case of U.S. Term Limits, Inc. v. Ray Thornton et al., 1994, the US Supreme Court ruled that states cannot impose qualifications for prospective members of Congress stricter than those specified in the Constitution. The case arose when Arkansas passed an amendment to its state constitution limiting terms served by elected officials at both federal and state levels - three terms for representatives and two terms for senators in Congress. This was challenged by several politicians including Ray Thornton who argued it violated their rights under Article I of the Federal Constitution which sets out requirements to serve as a member of Congress but does not include term limits. The court held (5-4) that allowing individual states to set additional or different qualifications would result in a patchwork effect where each state could potentially have different rules governing eligibility criteria thus undermining uniformity intended by framers of the Constitution regarding Congressional service qualification standards.

In the dissenting opinion for U.S. Term Limits, Inc., v. Ray Thornton et al., Justice Clarence Thomas argued that the Constitution does not prohibit states from setting term limits for their congressional representatives. He asserted that while the Constitution sets minimum qualifications for office, it doesn't explicitly set maximum ones and therefore leaves this power to individual states under the Tenth Amendment's reservation of powers not delegated to federal government or prohibited by it to States or people. Furthermore, he contended that historical context supports this interpretation as several states had restrictions on terms during ratification debates without any objections raised about constitutionality. Finally, he disagreed with majority’s view of democratic principles being violated by term limits arguing instead they could enhance democracy by preventing entrenchment in power and promoting citizen participation in politics.
