body: Is there any legal mechanism for a citizen without resources, to be able to sue the state for infringing his/her constitutional rights? In Argentina for example, I know there is a "defensor del pueblo" at national and provincial level, but as far as I know, he acts by his own and not by petitions besides they are a few for so many people.
  
  
  I don't know if here questions can be asked about how it is for more than one country, my interest is worldwide and more particularly Latin American countries, since certain types of freedom of speech/beliefs/equality under the law, fair trial, etc. abuses, and constitutional violations by part of international lobbys inserted and exercising its influence from inside of the states are seen across most western countries.
