[JURIST] Ukraine's Justice Minister Serhiy Holovatiy Monday appealed a Friday court ruling that reinstated [JURIST report] Svyatoslav Piskun as Ukraine's prosecutor general. Piskun was fired by President Viktor Yushchenko [BBC profile], allegedly for investigating the finances of Yushchenko's wife [JURIST report], but was reinstated after a court found his dismissal illegal. Yushchenko claims the termination occurred because of "ineffective work" and Piskun's failure to solve several high profile cases, including the murder of an investigative journalist and Yushchenko's own dioxin poisoning. Ukraine [JURIST news archive] currently has two top prosecutors, as the appointment of Piskun's replacement, Oleksandr Medvedko, was approved by parliament last month. UNIAN [media website, in Ukrainian] is reporting that guards at the General Office of Public Prosecutor have refused to allow Piskun to enter the building [ForUm news report] as he attempted to report for work Monday.
