⚠️ Editor's Note: No new court rulings were collected since April 12, 2026. The following summarizes legal implications mentioned in recent reports.
① Personal Information Protection Act Amendment (Passed Feb 2026) — Clarifying Executive Liability
The amendment passed by the National Assembly on February 12, 2026, mandates that business owners or representatives are legally obligated to ensure the effective implementation of management measures, including securing professional personnel and sufficient budgets for data protection. This effectively shifts responsibility from individual practitioners or CPOs to the executive level.
② Joint Amendment of Privacy and Network Laws — Mandatory ISMS-P Certification
According to a column by Jipyong in the Law Times, the new amendment mandates ISMS-P certification for designated data controllers. To allow for budget and resource allocation, this will be effective starting July 1, 2027. Additionally, strengthened requirements for breach response under the Information and Communications Network Act take effect in 2026.

③ Lexology — Implications for CPO Roles and Mandatory Certification
An analysis on Lexology suggests that the amendment aims to "strengthen the responsibility of business owners while guaranteeing the practical authority of the CPO to bolster preventative measures." Companies will face increasing pressure to provide CPOs with independence and real decision-making power.
