Justice C V Bhadang quashed the order passed by the 'Central Prescribed Authority', holding that Silva was a Portuguese citizen as his birth was registered in that country (Portugal).
Silva, who is a Goa Vikas Party (GVP) legislator, represents Benaulim constituency in South Goa.
The high court remanded the matter back to the MHA, asking it to once again hear it "as expeditiously as possible and preferably within a period of three months from the receipt of this order".
The order was challenged by Silva.

While passing the order, the court observed that the petitioner is a registered voter from Benaulim Constituency for the Legislative Assembly of State of Goa and that the petitioner holds an Indian passport.
The court noted that the petitioner had not given any kind of declaration to the Goa administration to retain Portuguese citizenship or nationality.
Silva had informed the high court that the Union Ministry, while passing the order with regard to his citizenship, had not given him the hearing, which was in violation of the principle of natural justice.
The counsel for Silva had submitted that at no point of time the petitioner had voluntarily or otherwise applied for acquisition of Portuguese nationality.
