The revised Nationality Law cleared the Diet Friday but only after lawmakers at the last minute managed to have a clause inserted to prevent what they claimed would be a surge in bogus paternal recognition cases.

The revised law cleared the Upper House with the nonbinding clause, which calls for applicants to submit pictures of offspring and fathers taken together to prevent false paternal recognition.

The resolution, which was revised from the version submitted by Lower House members, urges the Justice Ministry to report to the Diet every six months on its enforcement of the revised law.
