Joan Street & 7 ors v Luna Park Sydney Pty Ltd & 1 or

The plaintiffs, Joan Street and six others, commenced proceedings against Luna Park Sydney Pty Ltd and another defendant. The dispute arose from an incident where the plaintiffs were allegedly injured while using the "Screaming Demon" ride at Luna Park. The case was heard in the Supreme Court of New South Wales. The central legal issues involved the admissibility of evidence obtained through subpoenas and notices to produce, as well as the standing of the plaintiffs to apply to set aside these orders.

The court had to determine whether the plaintiffs had the necessary standing to challenge the subpoenas and notices to produce, and whether the evidence obtained through these means was relevant to the case. The plaintiffs argued that the evidence was irrelevant and that they lacked standing to apply to set aside the subpoenas. The defendants, on the other hand, contended that the evidence was relevant and that the plaintiffs had standing to challenge the orders.

The court found that the plaintiffs had standing to apply to set aside the subpoenas and notices to produce, as they were directly affected by the orders. However, the court also determined that the evidence obtained was relevant to the case, as it pertained to the operation and maintenance of the ride in question. The court ruled that the subpoenas and notices to produce were valid, and the evidence obtained through these means could be admitted. The plaintiffs' application to set aside the subpoenas and notices to produce was dismissed.

The court ordered that the subpoenas and notices to produce be enforced, and the evidence obtained through these means be admitted as evidence in the case. The plaintiffs were also ordered to pay the defendants' costs associated with the application to set aside the subpoenas and notices to produce.
