Out of a panel of 30 people, seven men and five women were sworn in as jury members.
Two women were selected to sit as reserve jurors until the end of the prosecution case.
Judge Andrew Menary KC told them: “This case concerns allegations arising from events connected to Mr Doyle’s conduct or alleged conduct at the Liverpool Football Club parade.
“The incident, as you may already be aware from general public knowledge, occurred in a busy city-centre setting and was subject to public attention.”
He said the nature of the case made it “especially important” that they stick to the rules and not pay attention to information from social media, the news or anywhere else.
Judge Menary said they should try Mr Doyle only on the evidence shared in court.
“Nothing else forms part of this case,” he said.
Jurors were told Paul Greaney KC will begin opening the prosecution’s case on Wednesday.
