Under that Doad, i was charged for being a member of a political party.
Are you sure about that?
You were likely charged for failure to submit a DND 2839 (which would fall under 129).
As per the Defence Ethic Program:
4. When and to whom am I required to submit a confidential report?
You are required to submit a Confidential Report (DND Form 2839E) to the COI Section, in any set of circumstances where you own a non exempt asset, practice of an outside activity or employment, or participate in political activities, regardless of your functions in the political organization and or its jurisdiction (band council, school board, municipal government, provincial or territorial legislatures or federal politics). This includes participation on election or re-election committees or being a volunteer for a political formation.
