The Federal Court on Tuesday gave a green light to Seven Network's $3 billion merger with Kerry Stoke's industrial firm WesTrac.

According to Justice Peter Jacobson who made the decision for both firms, he found nothing unusual with the findings of the proposals.

"There's nothing to suggest that the unrelated shareholders or the TELYS3 holders voted otherwise than in good faith," Justice Jacobson said. "Or they cast their vote for any improper purpose. The test of reasonableness appears to be satisfied."

The Federal Court was due for a decision today regarding the proposed tie-up. The approval was the final barrier for the merge to complete.

A total of 88.7 per cent of Seven Network's shareholders gave its approval on the merger of the media company and the Perth-based WesTrac last week.

Shares of Seven Network will be suspended from trade on the Australian Securities Exchange on April 29 with WesTrac, and be renamed Seven Group Holdings Ltd (SGH), to trade on a postponement settlement basis the following day.

The new company will penetrate into the resource service sector and expand its presence in China through its partnership with the WesTrac group.

WesTrac is also an authorized Caterpillar dealer in Western Australia, New South Wales, the ACT and north-western China.

Kerry Stoke, owner of WesTac and also an executive chairman of Seven Network, will emerge with 68 per cent of the new company. He said that the partnership will further present bigger opportunities for growth, and there will be future developments in terms of media, investments, and equipment management.

Last week, Peter Ritchie, deputy chairman of Seven Network, said that WesTrac would catch up as SGH's main business media for the coming years.

"The WesTrac side of this organization is going to be the core of it in five years' time - mark my words," Ritchie said.

Seven Network holds 47 per cent stake in Seven Media Group, which is a partner of Kohlerg Kravis and Robers that broadcast TV stations; and a 50 per cent stake of Yahoo!7.

Shares of Seven increased to 11 cents or 1.43 per cent, to $7.79 earlier today.
