Back on track, amended court date (edited):
The PX and R.L. appeal against the judge’s original decision to join the parties together will be heard in Supreme Court Waigani on September 7th.
This is called a directions hearing.
For this hearing PX has prepared what is termed their "appeal book" which is as it's name suggests is a book containing all the documents which PX will be relying on to support their appeal.
At the Directions Hearing on 7th the judge will confirm the appeal book and decide on a date for the hearing.
This may be in October, but more likely in November, as the court books are chokkers according to the solicitor.
