My understanding is that the U.S. Court of Appeals for the Tenth Circuit has consistently taken the view that when a state has restored the RTKBA - the relevant STATE FELONY CONVICTIONS are not predicate for application of 18 USC, SEC. 921/922 (federal POWPO statute). The 10th Circuit has clearly held that the 1994 amendment of CRS 18-12-108 DOES NOT NEGATE any prior restoration of rights under Article VII, Section 10.
In the case of Colorado felony convictions the 10th Circuit has interpreted the TOTALITY of Colorado law on this subject holding that CRS 18-12-108 only restricts the RTKBA for TEN YEARS FOLLOWING COMPLETION OF SENTENCE. This interpretation only applies to federal POWPO law.
Unfortunately, the State's official position maintains that the restriction is life-long. Regardless of this confusion, the Article 13 RTKBA affirmative defense remains available.
This restoration of ALL RIGHTS issue still awaits full vindication in Colorado courtroom as it pertains to eligibility for a CO CHP.
The main caveat to the constitutional affirmative defense in Colorado is that the previous offender is legally limited to in-home, and in-vehicle possession since public open carry presents the risk of complications such as menacing, trespass, or restricted locations violation charges that would negate the affirmative defense.
Concealed carry in Colorado without a permit would also negate the constitutional affirmative defense, and Colorado courts have yet to respect/recognize the "restoration" principle embodied in Article VII, Section 10 even though Michigan's restoration was honored in Seguna v Matejka.
The State of Colorado has exhibited some difficulty in recent years in coming to grips with the fact that the Colorado Constitution since its adoption in 1876 has in fact provided for the restoration of ALL RIGHTS OF CITIZENSHIP - WITHOUT EXCEPTION- once a convicted person has completed their sentence. The appellate court of late has become increasingly helpful in correcting this error.
In the absence of any collateral criminal offense, federal prosecution is not likely given the settled law stemming from 10th Circuit decisions regarding Colorado restoration of rights.
