Whether or not California defendants in a criminal proceeding have a court-appointed attorney or an attorney paid for with their own funds, they have a Sixth Amendment right to a fair trial and should expect to receive, at least, adequate legal representation. If the legal actions of an attorney during a trial reach a certain degree of negligence, a court could overturn a guilty verdict. However, the burden of proving the extent of legal negligence necessary to invalidate the outcome of a judicial process is very high.
