Legal Question in Criminal Law in California

I suppose it's possible for a person with no legal training to successfully appeal a case to the United States Supreme Court.

I've also seen movies where people are trapped on a desert island, a castaway gets sick, and a fellow survivor with no medical training removes his appendix with instructions given over a short wave radio.

Your chances of succeeding in a legal matter are much greater with an attorney who knows the rules.

Can you do this? Yes. Can you do it well enough to win? I very much doubt it.

Sure you can, in any court in the country. If you know what you're doing, and can effectively do so, good luck. If not, hire an attorney that knows how.
