Lawyers for Kazuo Okada, the Japanese billionaire Wynn Resorts Ltd. is trying to remove from its board, are scheduled to return to a Nevada court in October to argue for access to the casino operator's books.

Clark County District Judge Elizabeth Gonzalez in Las Vegas, according to a notice filed in court, scheduled a hearing for Oct. 2 on arguments whether Okada's request for documents, including ones regarding Wynn Resorts' dealings with Macau officials going back as far as 2000 and the company's use of $120 million he invested in 2002, is reasonable.

The judge at a hearing in June deferred a decision until Wynn Resorts' lawyers had a chance to quiz Okada, 69, about the purpose of his request. Wynn Resorts' lawyers have argued that Okada is using the petition as "back-door discovery" to collect evidence to use in Wynn Resorts' lawsuit against him, in which the two sides can't yet request documents.
