As per statement of the petitioner made in the written statement, he was born on10.09.1977 at Gobindapur under Dharmanagar Police Station in Tripura and in hisevidence, he stated that during his childhood, his father had shifted to Karimganj district but in Ext.2, there is no mention about Babulal Namasudra, the petitioner. This document does not indicate that petitioner is a family member of Rai Mohan Namasudra. Therefore, this belies the contention of the petitioner that he was born at Gobindapur in Tripura. What happened to Kamini Namasudra? We do not know. His wife, i.e., the projected grandmother of the petitioner is also conspicuous by her absence in both Ext.1 and Ext.2. There is nothing on record to establish linkage of the petitioner either with Rai Mohan Namasudra or with Kamini Namasudra. In such circumstances, it is quite evident that petitioner had failed to establish linkage with an Indian parent or grandparent relatable to a period prior to 25.03.1971 which is the cutoff date for identification of foreigners in the State of Assam as per Section 6A of the Citizenship Act, 1955, as amended. Thus, it cannot be said that petitioner had discharged his burden under Section 9 of the Foreigners Act, 1946.
