I think you misunderstand what hearsay means Eleanor. Pavia received a direct call from Kate. He wasn't told about it by a third party so how in heaven's name can it be hearsay ?
I'd be interested in JP's view.
For the moment, I think that Eleanor is correct - i.e., that it's hearsay.
Not that Paiva heard it from a different party, but that there was no direct proof presented as to what Kate is alleged to have said. If the phone conversation had been recorded, or an email / fax / letter presented, then that would presumably have counted as substantiated evidence. Not that this was a criminal court case anyway.
I've never understood the big deal about it. So what if Kate had had a nightmare that her child could have been dumped in x, y or z location? She could have had a nightmare about a masked pygmy or an alien abduction... what was being read into this?
There's ample room for a "misunderstanding" about a dream / nightmare / some psychic's vision / a potentially inadequately investigated possibility... whatever.
