That's for the first nation itself to determine.
Prior to 2014, of course, under section 82 of the Indian Act, all bylaws had to be submitted to the minister for review, and there was a power of disallowance. If the bylaws were not charter-compliant, the minister would typically disallow them at that point.
Since that power has been removed, the minister has no oversight authority over those bylaws, so it is up to first nations to determine the content of those bylaws, and they no longer have to submit them to the department for review, approval, disapproval or any process like that.
