Monaghan Councillor Hugh McElvaney will appear before the Standards in Public Office Commission again today as the organisation recommences its hearings into his case.
The hearings began in September 2018 after three Councillors featured in an undercover investigation into planning.
This investigation was launched after Councillor McElvaney appeared in an RTÉ undercover investigation into planning.
An undercover reporter posed as a representative of a foreign firm planning wind farms across the country.
In last year’s hearings he claimed he had been effectively “entrapped” and “enticed to say what he said in the programme” by a “blonde and attractive woman”.
They also claimed the featuring of a Principal Officer with SIPO in the programme called into question the integrity of the investigation.
The hearings were adjourned to allow Councillor McElvaney take a case to the High Court, claiming that SIPO should be stopped from going any further.
In September, Mr Justice Garrett Simons, who heard the application over the course of two days, said he was satisfied “to dismiss the application in its entirety.”
The SIPO hearings will get underway in Dublin this morning.
Hearings have already taken place into two other Councillors featured in the same undercover investigation.
