ASADA joy at Ian Robson quitting, says Essendon clubman

ASADA investigators have been accused of "celebrating" the resignation of Essendon CEO Ian Robson.

Ian Robson was a high-profile casualty of the Essendon supplements saga.

AUSTRALIAN Sports Anti-Doping Authority investigators have been accused of "celebrating" the resignation of Essendon chief executive Ian Robson.

A club psychologist says he witnessed the "highly unprofessional and concerning" behaviour during ASADA interview sessions with Essendon's players at Etihad Stadium on May 23.

Jonah Oliver's official complaint is detailed in an email sent to club chiefs seen by the Herald Sun.

"Today ... I witnessed behaviour from two ASADA investigators that concerned me," the Oliver email says.

"I was in the corridor ... when the interview door flung open and a tall gentleman said words to the effect 'have you heard the news, Ian Robson is resigning at midday!' At that time a second person ... said words to the effect 'that's the first one'. While it is hard to convey intonation and meaning, it was clear that both ASADA staff were excited by the news."

News_Rich_Media: AFL Chief Executive Andrew Demetriou denies there was a secret deal done with suspended Essendon coach James Hird, but admits he doesn't know everything.

Oliver said he was disgusted by the incident and felt compelled to report it.

"The reason for the email is that it concerned me that people involved in the investigation may not be simply in the pursuit of truth, free from any agendas. I appreciate that I am inferring things here, and may be emotionally involved in the case.

"However, I feel their words and emotional affect appeared highly unprofessional and concerning. In lay terms it felt like they were celebrating Ian's resignation, rather than merely conveying the news of his impending resignation."

Robson has since taken up the post as chief executive of Melbourne Victory.

ASADA did not respond to questions.

News_Rich_Media: Reports have emerged suggesting former Essendon coach James Hird was offered a peace deal to drop his legal case against the AFL.

ASADA's joint investigation into Essendon with the AFL began in February but appears no closer to a resolution.

An interim report was handed to the AFL in August but made no findings or recommendations.

More than 110 witnesses have so far been interviewed and over 13,000 documents gathered.

Despite new powers compelling Stephen Dank to speak to ASADA investigators, the sports scientist at the centre of the Bombers drugs probe is yet to be questioned.
