I just reread the article. The drafting error is in the proposed order granting relief, which is bad but not fatal as it would have been in the motion's relief request. The judge has to let the other party comment on any nunc pro tunc changes in the proposed order. That's where the delay comes in.
Lawyers are paid big buck$ not to make such mistakes.
How long should the comment window take? It seems like the spirit of the law is getting tossed out the window; the complainee knew exactly what the complainant intended, whether it was punctuated precisely or not.
