Story summary

In a recent ruling, NSW Supreme Court Justice Ian Pike harshly criticized ex-wife Lisa Rothner, ordering her to pay David Waterhouse's legal costs on an indemnity basis. This order is significantly more severe than ordinary costs and could leave Lisa responsible for the majority of Waterhouse’s legal expenses related to the case. The conflict centers around the sale of Villa Biscaya, a Spanish-style mansion in Rose Bay, Sydney, which has featured prominently in reality TV shows like Married At First Sight and The Bachelor. This latest development marks another dramatic turn in an already contentious property dispute that has involved several high-profile figures, including investment banker Michael Rothner.

Investment banker Michael Rothner and his ex-wife Lisa (pictured together) were embroiled in a bitter dispute involving a multimillion-dollar property deal David Waterhouse (pictured) is the estranged brother of bookmaker Rob Waterhouse, uncle to Tom and Kate Waterhouse, and brother-in-law to horse trainer Gai Waterhouse The WhatsApp messages as described in the Supreme Court judgement, mocked up here As the Daily Mail's Lucy Manly previously revealed, the judge found Michael Rothner had authorised Lisa to oversee a covert tree-clearing operation involving contractor Al Shahwan, rejecting his claims that he knew nothing about the scheme. uncertain
he → picture → scheme
The proceedings unearthed a remarkable cache of WhatsApp messages between the former couple, including discussions about ensuring there was 'no evidence' left behind and removing rubbish from the site. asserted

Justice Pike ultimately found Lisa was the 'architect' of the tree removal operation and described the destruction of the trees as 'an act of vandalism unconnected with the carrying out of authorised works on the property'. asserted
Lisa → find → property
But it is the newly published costs judgement that contains some of the court's most pointed observations. asserted
that → publish → observations
While Waterhouse and Rothner escaped having to pay each other's legal costs after each enjoyed only mixed success in the litigation, Lisa fared considerably worse. asserted

she → accord → allegations
The court had previously noted it would have been 'natural' for Michael to call Lisa as a witness about the tree-clearing operation and whether he authorised it, but she never took the stand. asserted
she → note → stand
One passage is likely to attract particular attention in legal circles. asserted
passage → attract → circles
'I think there is considerable force in the submission advanced by Mr Waterhouse that Mrs Rothner participated until the point in time she had to choose whether to further perjure herself or not, and made an informed choice not to do so,' Justice Pike said. asserted
Pike → think → choice
The judge did not make a finding that Mrs Rothner committed perjury and Inside Mail does not suggest anything to that effect. asserted
Mail → make → effect
However, the extraordinary remark formed part of a broader criticism of her conduct in the proceedings and helps explain why she ultimately emerged as the biggest loser in the Villa Biscaya saga. asserted
she → form → saga
The development marks a significant blow for the eastern suburbs socialite, who remains closely associated with Villa Biscaya despite the breakdown of her marriage to Rothner. asserted
who → mark → Rothner

he → reveal → roof
Any suggestion the split was seamless wasn't helped by what happened next. asserted
what → help → ?
Swan, who missed Charles' final week in the office while recovering from surgery, somehow found time to stay completely silent about his departure on Instagram. asserted
who → miss → Instagram
That changed only after Inside Mail approached Nova's PR team for comment, prompting a hastily assembled farewell post to appear on her feed. asserted
Mail → change → feed
Now comes another curious development. asserted
development → come → ?
Swan's continued absence has tongues wagging that all may not be well on The Chrissie Swan Show without her trusted lieutenant by her side. uncertain
all → continue → side
We're told the drive program is beginning earlier, at 3pm, effectively erasing Swan's lucrative 2-4pm school pick-up slot from the schedule. asserted
program → tell → schedule

Swan → tell → feet
Nova execs will certainly be hoping so. asserted
execs → hop → ?
