I need some help locating Colorado case law in reference to the use of a credit reports to verify or validate debt in court.

At trial I objected to the use of my cr as hearsay because there isn't any one from that credit reporting agency in the court that could testify to those records and that cr are often wrong and they shouldn't be allowed to be admitted as evidence. The judge over rules and allowed it to be admitted.

If anyone can tell me the best way to locate a similar case?
