Netherlands v Sweden ,1958 ICJ 8, (also known as the Boll case) was heard before the International Court of Justice in 1958.

It remains the only case in which a Convention drafted by the Hague Conference on Private International Law was the principal subject of interpretation by a court with worldwide jurisdiction.

Swedish authorities overrode the Dutch decisions and placed the child under a protective public care order, based on the fact that Marie was residing in Sweden with maternal grandparents.

As such, the 1902 Convention did not prevent institutions of public law, here the Swedish order, from intervening to take the child into "care" or "protective upbringing."

In response to the decision, the Hague Conference, which had recently created a small Permanent Bureau, responded by drafting a new Convention in the Conference's Ninth Diplomatic Session in 1960, the Hague Convention of 1961 concerning the powers of authorities and the law applicable in respect of the protection of minors, which included expanded language regarding "measures directed to the protection of [the child's] person or property," which was specifically intended to apply to both a state's own private law orders, such as guardianship orders, but also to all public care orders.
