AP Syllabus focus:
‘Life tenure helps justices act independently of current politics. This independence can produce controversial or unpopular decisions that spark debate about the Court’s power.’
Life tenure is a core structural feature of the federal judiciary intended to protect judges from short-term political pressure.

Understanding how it works explains both judicial independence and why some Supreme Court decisions provoke legitimacy debates.
What Life Tenure Is and Why It Matters
Federal judges (including Supreme Court justices) do not serve fixed terms. Instead, they typically remain in office for decades, which shapes how they decide cases and how other political actors respond to the courts.

Life tenure: A system in which federal judges hold office for life (under “good behavior”) unless they resign, retire, or are removed through impeachment and conviction.
Because justices do not have to campaign, seek reappointment, or satisfy voters to keep their jobs, they can decide cases based on their interpretation of the Constitution and law rather than electoral consequences.
Judicial independence as an outcome
Judicial independence is the practical ability of judges to make decisions without fearing political retaliation. Life tenure supports independence by reducing incentives to tailor rulings to popular opinion, party leaders, or the president who appointed them.
Constitutional Foundations That Protect Independence
Life tenure is not an accident of tradition; it is a deliberate constitutional design choice to insulate courts from day-to-day politics.
“Good behavior” and stability
Article III’s “good behavior” standard creates strong job security:
Judges are not routinely removable for unpopular decisions.
Courts can maintain consistent legal reasoning across administrations and election cycles.
Justices can take long-term views of constitutional meaning, even when short-term politics point the other way.
Salary protection and insulation
Another key protection is that federal judicial compensation cannot be reduced while a judge remains in office. This limits a major avenue of political pressure:
Congress cannot punish specific rulings by cutting a judge’s pay.
The judiciary is less financially dependent on approval from elected branches.
How Life Tenure Shapes Judicial Decision-Making
Life tenure affects both incentives and the kinds of cases courts can decide without fear of immediate backlash.
Reduced electoral incentives
Because justices do not face elections:
They can protect minority rights even when those rights are unpopular.
They can enforce constitutional limits on the political branches without worrying about losing office.
They are less directly responsive to sudden shifts in public opinion.
Long time horizons and doctrinal development
Long service allows individual justices and the Court as an institution to:
Develop consistent interpretive approaches over many years.
Influence constitutional law across multiple eras of political change.
Create continuity that can outlast any single president or Congress.
Independence and Controversial or Unpopular Decisions
The syllabus focus highlights a key tension: independence can produce rulings that large parts of the public oppose.
Why unpopular decisions happen
When legal reasoning conflicts with majoritarian preferences, the Court may still rule based on:
Constitutional text and structure
Prior legal principles and judicial reasoning
The view that some rights and limits are meant to restrain majority rule
Why that triggers debate about the Court’s power
Because justices are unelected and life-tenured, controversial decisions can spark questions such as:
Whether the Court is acting as an impartial legal body or as a powerful policy-making institution
Whether long-serving justices are too insulated from democratic accountability
Whether independence has become distance from the public rather than protection from political coercion
These debates intensify when the Court decides highly salient issues and the outcome diverges sharply from public expectations or prevailing political coalitions.
Independence Within Separation of Powers
Life tenure positions the judiciary to serve as an independent actor within a system of separated institutions sharing power.

The diagram is useful for seeing how the Supreme Court was framed as one component of a broader constitutional structure rather than a stand-alone political actor. Source
Checking political power without fearing removal
Independence makes it more plausible for courts to:
Reject unlawful executive actions
Invalidate statutes that conflict with constitutional requirements
Issue decisions that impose real constraints on elected officials
The trade-off: legitimacy versus insulation
Life tenure is a trade-off built into constitutional design:
Benefit: Courts can uphold constitutional limits even during political emergencies or intense partisan conflict.
Cost: The same insulation can make the Court appear unaccountable, especially when rulings are unpopular or politically consequential.
FAQ
“Good behaviour” is primarily a legal standard, not a broad moral test.
In practice, it means judges are not removed for unpopular rulings; removal is tied to serious misconduct addressed through formal constitutional processes, not ordinary political disagreement.
Life tenure tends to encourage presidents to nominate relatively younger candidates who could serve for many years.
It also makes each vacancy politically significant and somewhat unpredictable, because openings depend on retirement, resignation, or death rather than a fixed schedule.
Yes. Because there is no mandatory retirement age, retirement is discretionary.
Justices may consider:
health and workload
desired timing for a successor
whether they feel their work is unfinished
These considerations can make retirements strategic without changing the legal structure of life tenure.
Long tenure can increase the need for sustainable workload practices over decades.
Justices may manage workload through internal Court procedures (e.g., case selection norms and division of opinion-writing), but life tenure can also raise concerns about capacity during periods of illness or advanced age.
Term limit proposals usually argue that independence could be preserved while improving predictability and reducing the stakes of any single appointment.
Supporters often claim term limits might:
lower temperature of confirmation politics
ensure more regular turnover
reduce concerns about lengthy, unaccountable influence
Practice Questions
Question 1 (3 marks) Explain one way in which life tenure can increase judicial independence.
1 mark: Identifies a correct feature of life tenure (e.g., judges serve for life under “good behaviour” and do not face re-election or reappointment).
1 mark: Links that feature to reduced political pressure (e.g., less incentive to satisfy voters, parties, or elected officials to keep their position).
1 mark: Explains how this supports independent decision-making (e.g., enables rulings based on constitutional interpretation even when unpopular).
Question 2 (6 marks) Analyse how life tenure can both strengthen the Supreme Court’s role in the constitutional system and contribute to public debate about the Court’s power.
Up to 3 marks (strengthens role):
1 mark: Explains insulation from current politics (no elections/renewal).
1 mark: Explains willingness/ability to issue decisions that constrain elected branches.
1 mark: Develops analysis with a clear link to long-term stability/consistency in constitutional interpretation.
Up to 3 marks (contributes to debate):
1 mark: Identifies that independence can produce controversial or unpopular decisions.
1 mark: Explains why life tenure/unelected status can raise legitimacy or accountability concerns.
1 mark: Develops analysis by linking unpopular outcomes to heightened scrutiny of judicial power.
