The former boyfriend of a woman allegedly murdered on Phillip Island has denied killing her.

Disabled pensioner Sam Karamanis told the Supreme Court he did call Robyn Hall a “slut” after she admitted having sex with Paul Dalton but did not murder her.

Mr Dalton has pleaded not guilty to murdering Ms Hall on December 19 2012 at his brother Matthew’s Cape Woolamai holiday house on Phillip Island.

The case was thrown out of court after Justice Lex Lasry discharged the jury, saying that after “anxious consideration” he had decided there was no evidence to lawfully convict Mr Dalton.

Justice Lasry believed Mr Dalton had no case to answer on either the murder charge or the lesser alternative charge of manslaughter.

After his arrest, Mr Dalton told police he had argued with Ms Hall about telling their respective partners about their affair but he denied killing her.
