In the extensive and sometimes heated arguments over universal jurisdiction, Judge Baltasar Garzon, and national courts such as those of Spain, often missing is much scholarly information on the actual evolution and state of Spanish domestic law on universal jurisdiction, certainly in English and accessible to English language scholars.

The Swan Song of Universal Jurisdiction in Spain, 9 International Criminal Law Review (2009) 777-808.

The abstract is below the fold.
