You enter the court when called. You have not given up jurisdiction.
They ask your name (trick question) depending on your answer you
either hold or lose jurisdiction.
Take time to answer the question. If they ask you again say I am not
very educated in matters concerning the law. However I need a few
moments to sort out my thoughts. Shuffle some paper around look
busy.
ACT ! You are on centre stage.
Is that ok?
A long pregnant pause gets them nervous. The longer you take the
more nervous they get. The CPS will plead to the judge in order to
hurry you up; to make you lose your concentration. If the slug breaks
the silence, the game is over as far as you are concerned you have
already won.
At this point ask them to repeat the question. When he does, walk
over to the CPS slug look at him directly in the eye, and say the
following words very slowly and very clearly and above your normal
speaking voice. Say this "I am the President / Chairman and CEO
of the Corporation" quite close to the CPS slug.
Then step back, and watch him flee, after showing the judge his
open palms*. The judge is now left with the 800kg Gorilla, and he
sincerely does not wish to know.
As there is no prosecutor there is no case. Smile and ask the judge
if he has anything else to ask. Only do last bit if you have the
temerity to do it.
Otherwise just leave the court if there is no further objection.
QED, Game, Set and Match 3-0 to you.

* open palms means he does not wish to get his hands dirty.
Caveat Emptor:
I am not a lawyer nor do I give legal advice. The following has
been for your education and entertainment. Though I have used
this and have walked away the same may not be your situation.
