A South Korean court has accepted a petition by GM Daewoo seeking to ban Russian carmaker TagAZ copying one of its models.

The Seoul court banned TagAZ Korea from using or passing on trade secrets and from producing or selling engines and knockdown modules of its C-100 sedan.

Agence France Presse noted that two former GM Daewoo employees now working for TagAZ Korea were arrested in September for allegedly leaking core technology to the Russian firm.

One of them is alleged to have stolen 6,000 computer files containing information on GM Daewoo's Lacetti model. The data is believed to have been used to develop TagAZ's C-100 model unveiled in Russia this summer.

GM Daewoo said in a statement that the court acknowledged that TagAZ Korea had illegally obtained core product technology of the Lacetti and "used it developing, manufacturing, selling and exporting C-100 vehicles, and prohibited listed illegal actions by a preliminary injunction."
