In October, the brothers, who are among seven Ingebrigtsen children, wrote that they still felt discomfort and fear about Gjert and had to tell their story publicly because of intense media coverage in Norway about their split with him.
“We have grown up with a father who has been very aggressive and controlling and who has used physical violence and threats as part of his upbringing,” they said.
“We still feel discomfort and fear which has been in us since childhood.
“Two years ago, the same aggression and physical punishment struck again. It was the drop that made the cup run over.”
On Monday, Gjert’s lawyer, John Christian Elden, again maintained his client’s innocence.
“Concerning the dismissed charges, we concur that there is no evidence to suggest that Mr Ingebrigtsen has committed any act punishable by law,” he said in a statement to BBC Sport.
“Moreover, Mr Ingebrigtsen disputes the account of events that form the basis of the indictment and, as such, does not acknowledge any criminal wrongdoing.”
He added they intend to contest the claims “vigorously” in court.
