I wonder if this would stop the courts from applying Bush v. Gore - the ruling that elections must be determined based on rules in place before the election was held.
They would not intevene to overrule the Senate. Of that I am certain. When the R's had the power to seat R's who lost in cases of clear vote fraud, they did not. (B1 Bob Dornan vs. Linda Chavez). This does not mean the Dems will reciprocate, however. The Dems play hardball, the Reps play softball. The R's also allowed the Donks to fillibuster everything they wanted to, including various Bush nominations. Again, will the Dems act the same? Perhaps it won't be an issue because the R's won't fillibuster anything important. It would be nice to win this one. My bet is still on whoever the SoS of Minn. declaring the winner being seated.
