Article 166: Conduct of business of the Government of a State
In plain words
All executive action of a State Government is taken in the Governor's name. Orders authenticated as the Governor's rules specify cannot be challenged on the ground that the Governor did not make them. The Governor makes rules for conducting government business and allocating it among Ministers, except matters for the Governor's discretion.
