The nationwide residency registration network known as Juki Net is constitutional even though it contains personal information on residents without their consent, the Nagoya High Court ruled Thursday, upholding a lower court decision.
In the suit, 12 residents of Aichi Prefecture claimed that because local authorities provide personal information without their consent, the network violates their constitutional right to privacy.
"It cannot be said that information for identity confirmation is information that requires a high degree of confidentiality," presiding Judge Takeaki Noda said in rejecting the plaintiffs' claim.
"There is little likelihood the right to privacy will be violated," he added.
