Questions about dredging in the River Mersey will be raised in Tynwald this week.
When the court sits on Tuesday, North Douglas MHK John Wannenburgh will put two questions to Infrastructure Minister Tim Crookall.
He wants to know how much dredging near the new Liverpool ferry terminal will cost and whether it more or less than previously paid at the Pier Head.
Mr Wannenburgh will also ask who will carry out the task.
