That all depends on how the upper control arms are positioned.
If the upper arms are positioned parallel (or near parallel) to the lower arms, then a panhard bar will definitely help with lateral positioning in a solid rear axle car.
But, if the upper control arms are angled in, so that they converge near the center point of the rear axle (forming a triangle), then the control arms themselves serve to keep the axle located laterally, and a panhard bar would be redundant.
