SYDNEY, May 15 (Reuters) – A judge hearing an Australian class action lawsuit against Tesla on Friday questioned whether the Elon Musk-led automaker was taking the discovery process seriously and ​warned it could expect “a really bad time” if it failed ‌to cooperate.

Federal Court judge Tom Thawley gave the warning after a lawyer representing 10,000 Australian Tesla drivers complained that the U.S.-listed car company had produced just 2,000 documents after an eight-month discovery process.

The lawsuit filed by Brisbane-based law firm JGA Saddler ‌accuses ​Tesla of misleading Australian consumers about phantom ⁠braking, battery range and self-driving ⁠capability.

Tesla has said it does not mischaracterise its product.

At a pre-trial hearing, JGA Saddler lawyer Rebecca Jancauskas said the case required Tesla to provide documents concerning its engineering software, computer systems and complaints ​outside Australia, but the firm had so far received inadequate material.

“From what we’re getting, we can’t brief our experts,” Jancauskas told the court. “The ⁠paucity of discovery is what’s thrown a ⁠massive spanner in the works.”

Justice Thawley said it was ​reasonable to expect Tesla to produce detailed documents, adding that the carmaker ​had the right to request confidential or sensitive material be ‌redacted.

“I find it gobsmacking that only 2,000 documents have been produced and I wonder whether the exercise has been treated seriously,” he said.

He added that he believed “one would need to get into engineering drawings and reports ⁠that had been made from others, and into investigations that may or may not have been undertaken.”

Tesla lawyer Imtiaz Ahmed said the defence had manually ⁠reviewed some 100,000 documents ‌and was still to review another roughly 75,000. ⁠The carmaker was concerned about disclosing confidential and sensitive ​information, ‌including names of individuals whom the applicants’ lawyers could ​approach, he ⁠added.

Thawley gave the carmaker until July 31 to wrap up its discovery, adding that “if it’s inadequate, you can expect a really bad time, and I will get into what’s gone on and whether it’s been done appropriately.”

He scheduled another case management hearing for September 1.
