The following spring, in 1954, Collins testified on behalf of Westbrook Pegler in the case of "Reynolds v. Pegler", a defamation case arising from comments written in 1949 by Pegler against Reynolds. Collins gave evidence as to Reynolds's reputation as a writer, arising from Reynolds's book about Dupre. Reynolds's counsel, Louis Nizer, attacked Collins's credibility during cross-examination for his failure to give credit to other sources of evidence that exposed Dupre. Another witness from Calgary felt compelled to testify on behalf of Reynolds to counter Collins's testimony.
