It is probably no exaggeration to state that many cases are won or lost on the jury selection. Every lawyer is familiar with cases that were tried through to a jury verdict and following a motion or appeal, were retried to a different jury, with opposite results being reached. In many of these cases the witnesses, the testimony, and all of the facts remain the same-the only difference being in the jury and the result. Thus, the importance of the jury selection cannot be overestimated.
