(2) If, on a consideration of the report made by the prescribed authority, the Tribunal is satisfied that--
the person named in the application is not an illegal migrant or that the application is frivolous or vexatious, or has not been made in good faith, the Tribunal shall, after giving the applicant an opportunity to be heard, reject the application;
there are reasonable grounds to believe that the person named in the application is an illegal migrant, the Tribunal shall issue a notice accompanied by a copy of the application, to the person named in the application, calling upon him to make, within thirty days from the date of receipt of the notice, such representation with regard to the averments made in the application and to produce such evidence as he may think fit in support of his defence: Provided that if the Tribunal is satisfied that the person aforesaid was prevented by sufficient cause from making his representation and from producing evidence in support of his defence within the said period of thirty days, it may permit him to make his representation and to produce evidence in support of his defence, within such further period, not exceeding thirty days, as it may, by order, specify.
