Got me. It is pretty vague speaking to felony or misdemeanor. I'm not a lawyer, and have not found a clear definition.
Section 1-13 (General penalty listed earlier. 1 yr/ $999 max) is governed by;
31-16-101. Ordinance powers - penalty
(1) The governing body of each municipality has power to provide for enforcement of ordinances adopted by it by a fine of not more than one thousand dollars, or by imprisonment for not more than one year, or by both such fine and imprisonment.

Edit;
Nevermind all of that. Look at the back of your ticket. A copy of one is here
http://www.denvergov.org/Portals/626...%203.12.12.pdf Read the back, its a civil penalty that is grouped together with 'climbing on red rocks', and 'sledding, ice skating, and tubing'. He simply violated a Denver code of having a weapon on city park land.
The fine should have been listed on the face of the ticket. If not, a case could be made that your brother did not have 30 days from the date of issuance of the citation to when payment is due as stated on the reverse of the ticket. (If this was even the style of ticket he received)
