This document is a letter sent on January 17, 1979, to the Austrian Federal Chancellor Bruno Kreisky during his visit to Czechoslovakia. The signatories of Charter 77 and members of the Committee for the Defense of the Unjustly Prosecuted (VONS) express their gratitude for Kreisky's long-standing support for human rights and request his personal intervention on behalf of Dr. Jaroslav Šabata. Šabata, a spokesperson for Charter 77 at the time, was sentenced to nine months in prison based on fabricated and politically motivated charges. The authors of the letter emphasize that this act of repression is a direct attack on the activities of Charter 77 and the principles of the Helsinki Final Act regarding international coexistence. The request included detailed documentation of the case. The letter, signed by spokesperson Ladislav Hejdánek and representatives of VONS, demonstrates the effort of the Czechoslovak dissident movement to internationalize the issue of political prisoners and utilize diplomatic pressure from Western democratic states on the communist regime to protect civil liberties.
