Comision Legal Sol
= a group of voluntary lawyers that give legal advice for protesters, occupiers, etc and actual legal assistance, should you get arrested. They usually have a couple of lawyers on guard for the big protests.
" "15M has shaken up one of the pillars of the Western State: the legal establishment. The existence of The Comisión Legal Sol, (Puerta del Sol Legal Commission), was an impromptu creation on the first night of encampment, when one camper offered legal advice to another. This marks a shift towards collective methods in what is traditionally perceived as a very individualistic profession. In Spain, certain groups of lawyers were already pooling their talents, sharing resources and incentivizing the use of free licenses in their documentation. The arrival of 15M has multiplied this free, open and collaborative legal micro-utopia. " (http://guerrillatranslation.com/2013/05/16/spains-micro-utopias-the-15m-movement-and-its-prototypes/)
