Shiels hit out after escaping further punishment for being sent to the stand in a Rugby Park match against St Johnstone last month, when Dallas was fourth official.
Shiels has been accused of two rule breaches relating to comments made in the media after last Thursday's hearing, namely that he impinged upon the character of a match official and that did not act in the best interests of football by making "improper comments of an insulting nature".
The SFA charge stated that the offending comments were his allegations that Dallas had "fabricated" evidence for and during the judicial panel hearing and his claim that the official had acted in a "manipulative and devious" manner.
