I think it's probably harder for a plaintiff than a defendant to drag things out. I mean, from a formal point of view, what is their reason for not just brining on their matter?
this one I know... paperwork. You bury the other side in paperwork.
if each sub motion requires x hours and y forms to fill out then filling 20 sub motions takes longer and costs more then 2 sub motions.
If you have lawyer (and I can NOT say how strongly you need a good one) each of those costs money... not just to fill out and argue, but they get paid to research the law to make there arguments, they can charge for the paralegal helping them.
If you are doing it yourself you have to be BOTH good enough at research to find the cases to reference, and good enough of a public speaker to make a convincing argument that may need to be modified on the fly as you go AND the time to do these things yourself.
On Monday I have to run payroll for a few companies, and file some forms, and reconcile some books. Monday almost every week is my busiest day. Sometimes something comes up midweek (or god forbid on the weekend) that I need to drop everything and do right then.
An average Monday is a 10 hour day for me. An average Wednesday is 4ish hours for me. If something goes wrong on a Wednesday and I end up working 8-9 hours that is bad but not the worst... if something went wrong on a Monday I just might not have enough time to do it even if I worked 12-14 hours.
A few years ago (I want to say around 2018) I watched a place implode with computer issues. me and several others could just not work. When the systems came back and we could we were flooded... not just with that missed work but now extra steps and the work we should be doing anyway.
I imagine trying 1 against a corp law team feels like week after week of THAT feeling... the drowning in things to do and respond to. However we had and end in sight (get caught up or at least close) you may not be able to SEE the light at the end of this tunnel.
