I’m for it, but increasing the size requires a Congressional majority. Sadly, we’re not there. FDR took a run at it and fractured the party. The fear is that if Democrats are able to do it, then the next Republican majority will do the same. I don’t think this consideration has merit. They are likely to do it anyway should they have the ability when the court doesn’t have a right bias.
I think there are better ways to go about it. The whole structure is flawed as it concentrates a wealth of power to small amount of people. Something like using a lottery composed of the federal appellate court judges for each case. In theory, many cases could be tried simultaneously as there are about 180. Those bringing the cases would also not have insight as to the court’s composition. They’d have to rely solely on the merit of their case.
