The case concerned a child born to Polish parents in 2007. Custody was disputed. The mother and the father lived together in Poland from the time the child was born until the autumn of 2009, when the parties split up. Subsequently, the child lived with the mother while the father had access. In 2012, the mother married another Polish man resident in Norway. The mother then wished to move to Norway with her son, but the father did not consent to this. The mother did not succeed with an application to the Polish court to move her son to Norway, but nevertheless took her son there in mid-August 2014. In September 2014, the father claimed return of the child to Poland under the Hague Convention. The case was heard by Oslo County Court in March 2015 and the court held that the child should be returned to Poland. The mother appealed to Borgarting Court of Appeal.
