Notes and Comments


Comment to 2015 Restyling: All references to an “inference” have been deleted because this makes the Rule flow better and easier to read, and because any “inference” is covered by the broader term “opinion.” Courts have not made substantive decisions on the basis of any distinction between an opinion and an inference. No change in current practice is intended.
