Cement Australia (Exploration) Pty Ltd v East End Mine Action Group Inc

Cement Australia (Exploration) Pty Ltd commenced proceedings against the East End Mine Action Group Inc in the Supreme Court of Queensland. The nature of the dispute involved environmental issues related to mining activities, and the proceedings included the use of expert evidence. The court was required to determine whether to allow amendments to an agreed list of issues for expert witnesses. The list had been developed in consultation with the parties and the relevant experts during a Court Managed Expert Evidence (CMEE) process, and while the respondent agreed to and signed the list, they later sought to amend it, a request which was initially refused.

The legal issue before the court was whether the respondent was entitled to amend the agreed list of issues for expert witnesses after signing it. The court considered the principles of finality and fairness in the management of expert evidence. It was noted that the list had been developed through a process that involved all relevant parties and experts, and any changes to the agreed list could potentially disrupt the process and result in additional costs and delays. The court further noted that the respondent had not provided any compelling reason for the amendment, nor had they demonstrated that the proposed changes were necessary or appropriate.

The court held that the respondent was not entitled to amend the agreed list of issues for expert witnesses after signing it. The court emphasised the importance of finality in the management of expert evidence and noted that the respondent had not provided any compelling reason for the amendment. The court further held that allowing the amendment would undermine the principles of fairness and efficiency in the conduct of the proceedings. Therefore, the court refused to allow the respondent to amend the agreed list of issues for expert witnesses.

The court directed the parties to provide the relevant experts with the signed list of issues for their consideration in their meeting of experts and joint expert report. This decision highlights the importance of finality and fairness in the management of expert evidence in civil proceedings. It also underscores the need for parties to carefully consider the implications of any agreement before signing it, and to avoid seeking to amend it without compelling reason.
