"The founders intended lifetime appointments to last forever."
The Constitution states that federal judges 'shall hold their Offices during good Behaviour' (Article III, Section 1). This was written when average life expectancy at age 50 was roughly 70-73 years. The founders expected justices to serve 10-15 years, not 30-40. In the first century of the Republic, the average Supreme Court tenure was approximately 15 years. Today it's approaching 28 years — nearly double — because justices are appointed younger and live much longer.
The founders could not have anticipated the modern reality of strategic retirement timing, where justices wait for a president of their preferred party to leave the bench. This practice — which has become standard — converts what was designed as an independent judiciary into a partisan inheritance system. Justice Stephen Breyer was pressured by his own party to retire before the 2022 midterms. Justice Ruth Bader Ginsburg's refusal to retire during the Obama administration resulted in her replacement by a justice with diametrically opposite judicial philosophy.
Notably, the founders did not give lifetime appointments to any other government official. The President serves 4-year terms (limited to two by the 22nd Amendment). Members of Congress serve 2- and 6-year terms. The framers understood that accountability requires periodic renewal of public authority. The judiciary was the one branch where they chose tenure during good behavior — but in a context where 'lifetime' meant something very different than it does today.
Justices serving nearly twice as long as founders expected — a structural shift, not original design
