I think that it is more important for thoughtfulness than partisanship to be a priority in court. I think that it is a negative thing when people in court decides to be bias in case for political reason. Thoughtfulness in court is definitely more important in regards to the fates of people's lives.
I believe that thoughtfulness is more important that partisanship in court, because attorneys and even pro pers in the court system need to act civil to each other. A court is a formal place and needs to be treated as such. If people were required to be more formal, they would remember not to take the situation lightly.
The most important priority in court is, of course, truthfulness. That is the reason the court system is set up; to find the truth. Any other priority aside from that is a not even close second, and should not even be considered for comparison. This is the judicial system here.
If everyone in the world would show just a little thoughtfulness then the world would instantly be a much better place. It doesn't take a lot on anyone's part, just a little. Thoughtfulness in the court is no different. While partisanship is important, especially in the court setting, thoughtfulness can go a much longer way in the end.
Courts should follow the law and be thoughtful in their rulings. The entire reason for a court system is to be nonpartisan in the first place, even though federal judges are appointed and confirmed by politicians. There is no place for partisanship in a court system although some attorneys seeking certain outcomes in federal courts will file civil litigation with certain justices that may lean one way or another on a particular decision.
