The company said the court order says it may apply for damages and costs.
Green Acres was founded in 1991 and has over 600 franchisees throughout New Zealand providing home and garden care as well as commercial cleaning.
Green Acres chief executive Logan Sears said the company brought the case to protect its brand, intellectual property and franchise agreement.
"Franchising is a major contributor to the New Zealand economy," Sears said. "It promotes independent business ownership and business excellence. But for it to function effectively franchisors must have confidence that their agreements can be upheld. I hope that this result has set a precedent that will provide some certainty for the franchising sector, " Sears said.
The Ruebes lawyer, Lawrence Ponniah, said his clients were average lawn-mowing contractors and weren't wealthy.
Green Acres were out to "make an example" of them, he said.
He said it was "naughty" of Green Acres to talk about the matter because proceedings in arbitration are confidential.
"It's very dangerous for me to even talk about it...they shouldn't be talking about the arbitration," Ponniah said.
"Even though we would like to comment, we can't," he said.
