Fisker Coachbuild has won a legal battle against rival US niche carmaker Tesla Motors.
Tesla accused the design company of stealing confidential information and delivering substandard designs.
In November, an arbitrator in California found no evidence that Fisker Coachbuild used confidential information from Tesla in its work on the Fisker Karma plug-in hybrid sedan. Sister company Fisker Automotive plans to launch the car in 2010.
The car is a likely competitor to Teslas planned battery-powered sedan, which has been postponed by a year.
The arbitrator also ordered Tesla to pay the more than $1.1 million (about 853000) costs of the action.
When asked to comment on the lawsuit at the Detroit auto show last month, Tesla spokeswoman Rachel Konrad said: Thats all behind us now.
Citing strategy differences, Tesla Sales and Marketing Director Daryl Siry resigned from the company on December 2.
During an interview with Automotive News Europe in London in July 2008, he said he was determined to pursue the lawsuit.
