Over the past decades, significant changes in spatial planning policies and territorial govern¬ance have been observed across Europe. The analysis of comparative perspectives helps to understand the evolved practices and to use its outcome for cross fertilisation and shaping of spatial and territorial development policies. The study is concerned with an outcome of case studies regarding spatial planning-implementation practices and territorial governance in selected countries. The case studies within developed framework emphasises on (1) terri-torial governance issues and possible arrangements, (2) applied procedures, modes, planning tools and techniques, and (3) reasonable qualitative assessment of the planning environment and implementation of plans. A systematic, logical and comparative analysis of the outcome of consolidated evidence gathering concerning the implementation of spatial development plans and institutional performance is used for the research. The key results of the research show meaningful movements between command/control and consensus-oriented govern¬ances, shifts from just formal institutionalised planning towards complementing informal planning arrangements as well as movements between supply-led and demand-led planning in differently experienced countries.
