What is the effect of lay opinion evidence on a summary judgment motion?

I have already acknowledged the now well-established use of lay opinion evidence. I also acknowledge the need on a summary judgment motion to restrain the degree to which I weigh the evidence. Nevertheless, it is not adequate for a responding party who has adduced insufficient evidence to say that more and better evidence may be available at trial. See Perth Services v. Quinton et al., supra. The occasion is now for a party to put its best foot forward with specific facts and coherent evidence that will enable the judge to say there is an issue that is genuine and which possesses a real chance of succeeding at trial. Without such evidence, a party’s position may not withstand “a good hard look”.
