Spatial planning is one of key tasks of regional (voivodship) local government in Poland. A spatial development plan for a voivodship includes many aspects which need to be decided upon. However, the implementation of this plan is largely independent of the will of the local government. The theory of planning (including spatial planning) emphasises that implementation of the plan is an inherent aspect of planning. Therefore, the article analyses to what extent regional spatial planning can actually be considered planning.
