We all have been in the position of filing motions in-limine to admit or object to the admission of evidence. I do this frequently for its efficiency and help in forming my case as we advance. There are times when counsel, usually trial counsel, wants to preadmit evidence.
There are times I do not object to preadmission and times I object. A primary reason to preadmit evidence is for use in opening statements. Here is my thought on why counsel might object to preadmission.
The military judge erred in pre-admitting Prosecution Exhibit 1, photos alleged to have been of the complaining witness at an earlier age, and Appellant was prejudiced when trial counsel published the exhibit to the members during opening statement. The military judge put his imprimatur on the evidence before the defense had the opportunity to cross-examine the witness in front of the fact-finder. Later examination does not avoid the combined effect of the military judge’s imprimatur, the primacy and recency effect (which we are all trained about); and the human tendency to solidify in an opinion formed early on (cognitive dissonance).
