ISSUE: Whether or not the resolution disciplining Alejandrino is null and void?
FACTS: Senator Jose Alejandrino was declared guilty of disorderly conduct and flagrant violation of the privileges of the Senate for having treacherously assaulted Senator Vicente de Vera. He was deprived of his prerogatives, privileges and emoluments of being a senator. He filed mandamus and injunction against respondent Senate President Manuel Quezon from executing the said resolution and to declare the said resolution null and void.
RATIO DECIDENDI: Neither the Philippine Legislature nor a branch thereof can be directly controlled in the exercise of their legislative powers by any judicial process. The court lacks jurisdiction to consider the petition.No court has ever held and no court will ever hold that it possesses the power to direct the Chief Executive or the Legislature to take any particular action. Also, if the Court does not have any authority to control the Philippine Senate, it has likewise no authority to control the actions of subordinate employees acting under the direction of the same.
