Setting a term of, say, 15 years would ensure that federal judges would not lose all touch with reality through decades of ivory tower existence. It would also provide a more regular and greater degree of turnover among the judges.
Take a position. Do you agree or disagree that federal judges should serve lifetime terms?
First, title your post either “Lifetime Appointments Are Acceptable” or “Term Limits Should Be Set.”
Then, using the information gained in this module and the resources noted above, make your case. What are the pros and cons of lifetime appointments? Of term limits? Be sure to build your case with factual resources.
In your response to your peers, consider how well they justified their position, making use of available resources. Consider the following questions in your response posts:
Did they support their position convincingly with appropriate resources?
Which of their points make the most sense to you, even if you made a case for the opposing viewpoint?
