Gorbachev and the Velvet Revolution seemed to vindicate his earlier efforts to reform socialism. Unlike in the Czech lands, a Communist Party never reemerged in Slovakia after the Velvet Revolution. During his last years, Dub ek served as chairman of the former Czechoslovak Parliament and prided himself in his role as moderator and a source of moral authority. Some members of the SDSS have repeatedly claimed that Dub ek's crash was no accident but rather an incident orchestrated to keep him out of the political picture. Others have blamed jealous Czech rivals or have targeted Dub ek's potential rivals in Slovakia itself.
None appear to have had enough evidence to back such speculation.
On account of the ongoing controversy, the Social Democratic Party leadership requested a review of the evidence compiled during the previous Czech-led investigation. The recent inquiry by the Slovak Interior Ministry aimed to put to rest such conspiracy theories. After a detailed reevaluation,the Ministry has reaffirmed the conclusion of the previous Czech investigation that Dub ek's death was indeed nothing other than a tragic accident. The chief Slovak investigator, Jaroslav Ivor, told a group of journalists that no evidence of murder had been found. This occurs when a wet surface causes a car to lose traction and go out of control.
