In March, Ulvaeus was given permission from Gotland’s county administrative board to build in a protected area.
The decision granted an exemption from planning regulations designed to keep Sweden’s beaches and coastal areas open to the general public.
Special dispensation was given by Gotland county governor Marianne Samuelsson who was forced to step down from her post in the summer in a separate incident over building permission.
Taped recordings were leaked of her comments giving a local businessman preferential treatment for plans to extend his property in a protected beachside area.
A first appeal by The Swedish Environmental Protection Agency (Naturvårdsverket) was thrown out when the court agreed with the country administrative board’s decision, giving Ulvaeus approval to proceed with his plans.
A second appeal contests that decision and states that coastal protection regulations have been contradicted and that there is no reason for the dispensation already granted.
The Enivronmental Court may now consider the case for a final time.
