Committee Comment
The Committee finds that the Federal rules in this area are for the most part an accurate representation of Colorado case law, statutes, and the Rules of Procedure. The Committee opinion is that the rules as adopted provide a more flexible guide to evidentiary problems relating to authentication and identification and thereby avoid the necessity of the search for a "case in point." The rules would cover a number of cases and situations arising in trial, not currently reported in case law.
