Last week, the Helsinki Court of Appeal overturned a sentence from a lower court imposed on Kanerva for accepting bribes.
The court also overturned the sentences of three wealthy businessmen, Arto Merisalo, Tapani Yli-Saunamäki and Toivo Sukari in the case. The prosecution is seeking to appeal these rulings, as well.
If a prosecution appeal is granted, the charges related to Kanerva's election funding and the sponsorship of his lavish 60th birthday party will be heard by the Supreme Court.
The Helsinki Court of Appeal ruling last week also dismissed related bribery charges against the former chairman of Rovaniemi's municipal council, Ari Ruotsalainen. An appeal in his case is also to be filed.
