There is even a perfect little incident to show it off: FDR's Court Packing Plan.
After he was elected he passed a bunch of shit and created a bunch of garbage as part of his New Deal. A lot of it amounted to just welfare with shiny names and a bunch of them also had serious legal trouble with the rest of the US Law, Government and Constitution.
So people sued and challenged it, and eventually they went to the SCOTUS and it was declared unconstitutional/illegal/unlawful. Due to how it all went down the programs were started in late 1932, and challenges began in 1933 but the real results began to show only in 1935 and later. By the time the game starts he has lost a bunch of rulings (including losing 3 cases in 9-0 rulings in a single day in 1935) and is pissed off.
His reaction, much like that of Democrats of today when the court rules based on law and constitution instead of "common good" was to throw a bitch fit and
announce a plan to restructure the entire thing to make SCOTUS do as he wanted. Not just to add new justices, oh no, he was gonna do some real bulshit like adding one new judge for every 10 years a supreme judge was in power once they turned 70 and didn't retire and adding a whole new lower court. He went to his
propaganda broadcast Fireside Chat to shill this and present it as a new and better way to do things of course.
Tl;Dr it failed, and likely cost the dems the 1938 midterms as a lot of his own party Good Old Boys were quite against such plans.
The fact this isn't shown in the game at all despite how tense it could have gone if the cripple hadn't backed down is a disservice to HoI4.
