what does proposed jury instructions of defendant means

Each side gets to submit instructions which they would like read to the jury at the conclusion of their trial. The instructions are submitted to the Judge and he determines what is to be read to the jury. Jury instructions generally explain legal concepts or theories as well as tell the jury how they should consider such evidence. When you submit the instructions to the judge they are merely "proposed" since they have not been decided on by the judge yet. Each side wants their instructions read since generally they favor their client. So when it states "proposed jury instructions of defendant" it means the instructions the defendant submitted to the judge for the judge to consider reading to the jury. If you are at this point where you are headed to trial or are currently in trial I urge you to get counsel as soon as possible.
