"There are huge practical difficulties. Whether New Zealand will grant me legal aid is one issue - they have refused it thus far and I suspect in the name of 'winning the game' they will do their very best to prevent me personally being granted legal aid to represent Mark," Mr Hislop said.
"We can only hope that someone who has the ability to fund this might feel strongly about this apparent injustice to assist us to right this wrong. If I am to fight the retrial we will have to seek out backers with deep pockets because doubtless, as with the appeal, the Prosecution will have an army working on the case against us."
Mr Hislop works for London firm Doughty Street Chambers, which is arguably the leading law firm internationally on human rights and civil liberties issues and he has a strong background in human rights issues and got involved in the Lundy case by chance.
"I think when I read into the Lundy papers I began to get an increasing feeling of unease that something had gone wrong.
"The more I read regarding the science in the case the less convinced I was that the Prosecution scientists had got it right."
