Scheduling more than 20 cases in a half a day hearing is normal for most courts.
The usual practice is to call all the cases and to know how many of the lawyers are ready.
On a second call the actual conduct of the hearing happens. Accused are arraigned, pre-trials are conducted and trials continued.
Arraignment usually last 5-10 minutes depending on the manifestations of the lawyer.
Pre - trial conferences could last longer depending on the stipulations and pieces of evidence marked.
Trials could last from thirty minutes to an hour depending on the lawyer. Some lawyers conduct their questioning fast, crisp and direct. Others draw answers like they are drawing water from a stone and that takes time.
So what do you do when the judge is still hearing number 3 and and you are number 32?
1. Text your secretary all your instructions for the day. (At least you are doing something while you are waiting.)
2. Study the case folder of the case scheduled for that hearing. (I kid you not how many nuances you will notice if you have read the case folder for the nth time.In three hours you can read a three inch thick case file three times.)
3. Observe. ( Observing the conduct of hearings especially if the lawyers involved are old timers is often equivalent to half a semester of law school.)
4. Chat with fellow lawyers. ( Just for fun! I have rekindled old friendships just to kill time and my life is enriched, seriously.)
5. Read a book. ( I have seen a professor of mine read a novel while waiting. It will enrich your vocabulary! hehehe)
6. Pray. (Pray that twenty years from now you are still patient enough to not fidget, fret and curse while waiting and you have not experience all sorts of stress related illnesses due to all the frustrations brought about by waiting.)
