The Spanish government is the sole authority with jurisdiction over asylum and refuge. Your case will be decided by Spain’s Ministry of the Interior, on the initiative of the Inter-Ministerial Committee for Asylum and Refuge (CIAR).
Once your application has been accepted for processing, a decision on it ought to be reached within a maximum period of six months. However, the process usually lasts longer. If there is a delay, the authorities must inform you of the reason. Remember that you are entitled to consult your file.
