Because ink stamps are placed on birth certificates for different reasons, the representative of the high commission for Sri Lanka in Ottawa consulted for this request is unable to comment on the above question without examining a copy of the stamp (22 Nov. 1993).
According to a representative of the Tamil Eelam Society of Toronto, the Sri Lankan authorities usually place a round ink stamp on the front or a rectangular ink stamp on the reverse side of a photocopy or a new copy of a birth certificate to certify the authenticity of the document (22 Nov. 1993). Both stamps are in the Sinhala language (ibid.).
This response was prepared after researching publicly accessible information currently available to the DIRB within time constraints. This response is not, and does not purport to be, conclusive as to the merit of any particular claim to refugee status or asylum.
