Doc, we have a Judge here in Fort Worth that has the same no pagers/phones rule. ha,they must be brother/sister.
She once put an attorney in the slammer for a few hours for his phone going off, and he was trying a case at the time!
Umm, sorry, we will continue this case tomorrow, Mr. lawyer, that'll be a contempt charge, and gimme the phone...
If ANYBODYS phone/pager goes off, they forfeit it right then and there, and they can get it back at the end of the day. This is even for the spectators.
She can be a harda$$, but if you are straight, she is very fair. Just like you said, don't try and pull the wool, she's seen/heard it all.
