An Italian state prosecutor has asked
for the manslaughter trial over the death of Ayrton Senna to be halted.
Senna is seen by many as F1's greatest-ever driver
Prosecutor Rinaldo Rosini said the case could not proceed because of a statute of limitations on the original charges.
Three-time F1 world champion Senna died in May 1994 after his Williams crashed during the San Marino GP at Imola.
The original manslaughter case against key Williams team personnel ended in aquittals which were upheld in 1999. But the case was re-opened in 2003.
Italy's highest court ordered the case to be re-heard because of "material errors" in the appeals process.
The new trial opened on Wednesday in the northern Italian city of Bologna.
But prosecutor Rosini asked the panel of judges for the case to be
closed because of the statute of limitations.
The panel of judges is due to issue their ruling on 27 May.
Four other cases over the last 40 years involving fatal crashes at Italian motor events have all ended in acquittals.
