As one who has been involved in many committees and organisations, I find the move by this committee and government offensive. The role of a chairman it is to organize the committee and in the case of a vote, would be a deciding factor. 
The chair is to remain unbiased and not direct the committee by their personal views. 
This action is showing that both the committee and government is assuming that the individual in question can not act professionally and keep her opinions to herself as a chairperson. That is totally unfair as she has been a working member of the committee for years and has not caused any problems with other committe members as mentioned by them in many reports. 
This action is totally uncalled for and puts a real cloud over open government. IMHO
