What does this cover?

The Higher Regional Court of Hamburg has ruled that the right to be forgotten also applies to online archives. The implication of this decision is that operators of online archives may be obliged to make sure that archive entries cannot be found via search engines.

This decision also applies to cases in which an archive entry deemed to be interfering with privacy rights was originally deemed lawful due to an overriding public interest. In the current case, it was held that the public interest expired over time, allowing the privacy rights to prevail.

What action could be taken to manage risks that may arise from this development?

None - this is for interest only.
