I think the constitution says that federal judges serve “during times of good behavior”, or some such language. And that has been interpreted to mean that their appointments are lifetime appointments.

Anyone know more about this? I agree there’s no specific language that the appointments to the judiciary are for life, but that’s been the understanding of that language about “good behavior” throughout our history.

The appointments are for life. The purpose being that they will not need another job down the road and therefore would not be subject to political influence.

I believe there's plenty of dialogue stipulating that they are indeed life time appointments.

Here is the actual wording of Article II regarding justices:

The judges, both of the supreme and inferior courts, shall hold their offices during good behaviour, and shall, at stated times, receive for their services, a compensation, which shall not be diminished during their continuance in office.

"...hold their offices during good behavior..." and "...continuance in office.." imply they are lifetime appointments.
