In a landmark judgment delivered in April, Justice Nye Perram ruled in favour of DBC's "preliminary discovery" application requesting that ISPs, including iiNet and Dodo, disclose the identities of people it alleges shared the movie online. This equates to a total of 4726 account holders.

DBC apparently believes there is no one-size-fits-all approach to seeking compensation from alleged pirates, and its questions are designed to help calculate the fee it will seek from each. Justice Perram demanded the company confidentially submit to him its methodology so he could ensure individuals would not be taken advantage of.

In the US, DBC threatened legal action against account holders claiming they were liable for damages of up to $US150,000 in court unless settlement fees of up to $US7000 were paid.

Lawyers for DBC argued on Thursday that its letter and phone scripts should not be released to the public, as it could weaken its bargaining position if alleged pirates learned what to expect ahead of time.

Counsel representing the ISPs, Richard Lancaster, said the questions DBC intends to ask in its letters and phone calls are too strongly worded, especially since it doesn't know for sure that the individual has actually pirated the movie.
