Suggesting that Biden do "some thing" suggest that the author has had little or no exposure to the rules of civil procedure in any jurisdiction much less the suggested best practices.
I am not a lawyer but I have had some experience as a claims manager and litigation supervisor so I have some failurity with these issues.
First the plaintiff files the suit against the defendant.
Second the defendant is served with a copy of the petition and a summons to answer the petition.
When the defendant receives the suit with the summons the defense is assigned to defense counsel who refer the suit to determine what answers and procedures are appopiate.
The fist issue is to determine if the service of process is correct. Many times suits are erroniously filed against the wrong defendent or served incorrectly.
If the suit is served incorrectly then the appropriate response to that issue is not file file responsive pleadings with out waiving the right to file responsive pleadings on the plaintiff's pleading.
The next issue is to determine if the court where the suit has been filed has jurisdiction over the defendant and the issues pleaded.
If there are no issues as to jurisdiction on over the defendant and the pleaded issues the responsive pleadings will be filed which may include a coulter claim.
When the Plaintiff receives the counter claims the Plaintiff - defendant on the counter claim will repeat the steps outlined above on the counter claim.
Nhe next issue will be motions rearding various legal issues raised in the pleadings foloowed by discovery.
Discovery consists of filing interrogates (questions in writing that the opponent has to answer in writing followed by depositions of the parties and expert witness.
All of this takes time.
The defendant in this case is the state's where the issue is being litigated so Biden and the democratic party may not have standing to intervene.
BTW: The answerer date on a law suit is often 20 days or more so that is likely to be after the election is completed.
Then there are the issues of appeals all the way up to the state supreme court and then the federal supreme court.
Trump is using lawyers to protect his right to do a recount in Georgia.
Biden should respond with using data analysts to look for irregularities (there are always irregularities) in Georgia precincts and get his lawyers to help him to order
recanvasing in Georgia.
As I explained before about irregularities, there are always irregularities.
As I explained before, in Iowa Bernie found some 15 or 20 precincts and got them recanvassed. Other Democratic candidates (such as Biden, Warren, Buttigieg) to also do recanvassing.
If you let your opponent cherry-pick where data quality is to be improved in a close race, you will lose. You have to equalize it by making it fairer by being self-interested, asking for the same thing so that overall quality is improved but also specifically quality in your favor balances out improvements in opponent's favor.
Yes, it takes time. It takes time to do the data analysis, let alone the lawyering.
