Peters, who is currently in the city, will advice Procter and the two teams -- India and Australia -- on procedural matters during the hearing.
The ICC has taken the Australian team's allegations against Harbhajan very seriously as it is a level 3 offence.
When contacted, an ICC spokesman in Dubai confirmed that Peters had been asked to be a part of the proceedings.
The spokesman revealed that the British lawyer had assisted the ICC in some cases in the past and is regarded very highly by the legal fraternity.
"We are taking the whole issue very seriously and that is the reason why Nigel Peters has been asked to attend the hearing," the spokesman said.
Harbhajan was charged last night under Level 3 of the ICC's Code of Conduct following his run-in with Symonds at the Sydney Cricket Ground.
