The Supreme Court of Justice ruled in March that the government should apply reasonable balance in the distribution of state advertising. Ruling in a case brought in 2006 by Editorial Perfil, the country's largest magazine publisher, the court sought to rein in the government's long-standing practice of rewarding supportive news media with state advertising while punishing critical media by withholdings ads. Nonetheless, Perfil and other critics alleged that President Cristina Fernández de Kirchner, who won re-election in October, continued the system of unequal distribution. Relations between Grupo Clarín, the nation's largest media conglomerate, and the Kirchner government worsened in March after demonstrators, including members of the Teamsters, blocked trucking exits at Clarín's printing facilities, preventing the paper from distributing its Sunday edition. In December, Kirchner signed a measure bringing the country's sole newsprint manufacturer, Papel Prensa, under government regulation. Publishers groups said it was another attack on Clarín and La Nación, which own a majority stake in the company. Circulation of the national daily La Nación was also disrupted for several hours. The local press group Foro de Periodismo Argentino documented a series of abuses in the country's interior, including an attack on a radio journalist, a case of arson, and an episode in which a camera crew was fired upon. A federal court sentenced 16 former military members in October to jail terms ranging from 18 years to life in prison for the murder of journalist Rodolfo Walsh and 85 others during the 1976-83 Argentine dictatorship.
