C.R.S. § 6-2-107

In any injunction proceeding or in the prosecution of any person as officer, director, or agent, it shall be sufficient to allege and prove the unlawful intent of the person, firm, or corporation for which he acts. Where a particular trade or industry of which the person, firm, or corporation complained against is a member has an established cost survey for the locality and vicinity in which the offense is committed, the cost survey shall be deemed competent evidence to be used in proving the costs of the person, firm, or corporation complained against within the provisions of this article.
