The Kyiv Regional Court of Appeals has ordered prosecutors to resume an investigation into the death of a Ukrainian politician 15 years ago.
The April 24 ruling annuls a January decision by a district court to close the case.
Vyacheslav Chornovil, who was campaigning for president against the then-incumbent, Leonid Kuchma, died in a 1999 car crash.
The Interior Ministry initially determined that the wreck was "accidental." But Chornovil's relatives challenged the official version, and a new investigation was opened in 2011.
Chornovil's family says it wants the case to be redesignated as a murder investigation. Chornovil's son, Taras, says the family believes documents and other evidence exists showing that the death was not accidental.
