What is the test for a jury to be instructed on the general principles of law in a criminal case?

The general rule is that " ' "in criminal cases, even in the absence of a request, the trial court must instruct on the general principles of law relevant to the issues raised by the evidence. [Citations.] The general principles of law governing the case are those principles closely and openly connected with the facts before the court, and which are necessary for the jury's understanding of the case." [Citation.]' " (People v. Breverman (1998) 19 Cal.4th 142, 154.) "We determine whether a jury instruction correctly states the law under the independent or de novo standard of review. [Citation.] Review of the adequacy of instructions is based on whether the trial court 'fully and fairly instructed on the applicable law.' [Citation.] . . . 'Instructions should be interpreted, if possible, so as to support the judgment rather than defeat it if they are reasonably susceptible to such interpretation.' [Citation.]" (People v. Ramos (2008) 163 Cal.App.4th 1082, 1088.)
