In the 2009 EALD Symposium, a presentation and succeeding publication (Ekbäck and Kalbro 2011), identified situations where negative value effects for property owners, gener-ated by time-consuming infrastructure planning processes, were in conflict with Sweden’s commitments under the European Convention for the Protection of Human Rights and Fundamental Freedoms. The publication ultimately triggered amendments in the legislation on planning, acquisition and compensation for national roads and railroads. In the present paper, new situations are identified where again the Convention’s articles for protection of property and the right to a fair trial may be violated. The topic analysed and discussed concerns municipal planning for development of the built environment, resulting in planning blight, i.e. a reduction of property values in a particular area resulting from expected or possible future development or restriction of development. The particulars of a case study are compared to the standard planning model and the generic situation where the proposed land use leads to a local depreciation of property values compared to current land use.
