These counts are smaller than the citation total above because most of the 86 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“Such amendment of the pleadings as may be necessary to cause them to conform to the evidence and to raise these issues may be made upon motion of any party at any time, either before or after judgment.... If evidence is objected to at the trial on the ground that it is not within the issues raised by the pleadings, the court may allow the pleadings to be amended and shall do so freely when ... the objecting party fails to satisfy the court that the admission of such evidence would prejudice him in maintaining his action or defense upon the merits.”
