Annotator's note. Since § 18-5-102 is similar to former § 40-6-1, C.R.S. 1963, relevant cases construing that provision have been included in the annotations to this section.

Reasonable distinctions can be drawn between crimes prohibited by credit card and forgery statutes, and the existence of the specific statute regarding the misuse of credit cards does not preclude prosecution or conviction of appellant under the state's general forgery statute. People v. James, 178 Colo. 401, 497 P.2d 1256 (1972).

Circumstances sufficient to establish prima facie case of forgery. Duncan v. People, 178 Colo. 314, 497 P.2d 1029 (1972).

To satisfy subsection (1)(c), a document must purport to have legal efficacy that affects some right or status, and fraudulent letter to the prosecutor's office recanting the initial statement of events and purporting to contain the victim's signature meets statutory requirements, since the prosecutor would likely rely on the letter in determining whether probable cause exists to move forward with the prosecution, which would affect defendant's legal status in the pending criminal matter. People v. Cunefare, 102 P.3d 302 (Colo. 2004).

Evidence of giving a forged resident alien card to a police officer was insufficient to support a charge of forgery with the intent to defraud the immigration and naturalization service. People v. Miralda, 981 P.2d 676 (Colo. App. 1999).

Requisite intent to commit forgery can exist in case where defendant used a false written instrument prepared by another. Prosecution is not obligated to prove defendant either mailed the false instrument or explicitly directed another to do so on defendant's behalf. People v. Taylor, 159 P.3d 730 (Colo. App. 2006).

Section 42-3-133 does not preclude prosecution under this section for altering and displaying a temporary license plate; therefore, this section is an appropriate statute to prosecute persons who alter temporary license plates. People v. Stansberry, 83 P.3d 1188 (Colo. App. 2003).

Applied in People v. Smith, 195 Colo. 404, 579 P.2d 1129 (1978).
