As lawyers waited for Mr Justice Bernard Barton to arrive in court, a familiar face in unfamiliar attire momentarily appeared on the monitor behind the judge's bench.
Wearing a Notre Dame T-shirt rather than a trademark suit, Declan Ganley had just dialled in to the remote High Court hearing from Moyne Park, his mansion set on 40 acres in Abbeyknockmoy, Co Galway.
The 52-year-old entrepreneur, political activist and anti-abortion campaigner has been running his US-based communications technology business Rivada Networks from there since the lockdown in March.
The T-shirt was a nod to his youngest daughter Clementine, a student at the US Catholic University whose sports teams are known as "The Fighting Irish".
Mr Ganley is also a combative type. He founded a pan-European political party aimed at reforming the EU and came close to election to the European Parliament in 2009.
He was also one of the leading pro-life voices against the repeal of the Eighth Amendment two years ago.
He is quite religious and has spoken on social media of listening carefully to Pope Francis, who he regularly includes in his prayers.
Mr Ganley is also, to use his own words, "an experienced litigant". His appearance in the virtual courtroom on Thursday was to witness the end of a nine-year legal row with RTÉ.
The telecoms millionaire received a financial settlement and an apology from the broadcaster over Citizen Ganley, a Prime Time programme aired in 2008.
The apology related to one of eight complaints he made in a 2011 lawsuit, his claim words used in the report meant, in their natural and ordinary meaning or by way of innuendo, he was somehow involved in the mysterious death of an Albanian lawyer.
No apology was made in relation to seven other issues raised by Mr Ganley.
Sources have suggested a sum in the region of €200,000 was paid to him, with both sides paying their own legal costs. Specifics have not been confirmed by either party.
Despite the settlement, a statement issued by RTÉ struck a defiant note. It said the broadcaster stood over the journalism in the programme and was happy to clarify one aspect of it. "We are glad that after a decade of legal argument, a mutually beneficial agreement has now been reached on the matter," it said.
While his tone was jovial after the settlement was announced, Mr Ganley claimed the broadcaster had "learned no lessons at all" from his case and others.
"If you are funded by the licence payer, you can be like that. Meanwhile, I accept their formal apology read out in court and their cheque with a great big grin. To the degree that RTÉ learn no lessons at all from this, I would expect nothing else," he told the Irish Independent.
The programme was broadcast five months after Mr Ganley and his Libertas organisation came from nowhere to successfully campaign against the ratification of the Lisbon Treaty. Although it was eventually passed in another referendum in 2009.
As a new political force, many questions were raised about his background and rise in the business world.
Born in London to Irish emigrants who returned home to Glennamaddy, Co Galway, when he was 13, he left Ireland after doing his Leaving Cert and became quite wealthy in his 20s. He was involved in enterprises in Eastern Europe, such as aluminium sales and forestry in Russia and Latvia.
However, an air of mystery surrounded his rise in the business world.
The RTÉ programme aimed to shed light on the Ganley "enigma", his business interests, his motivations and the source of Libertas's funding.
Mr Ganley did not like what he saw and legal proceedings followed. The case became protracted as it got bogged down in pre-trial wrangles.
RTÉ complained about the non-release of documentation and a court ruled it could cross examine the businessman over deficiencies in discovery. Mr Ganley claimed documents related to his Anglo Adriatic Investment Fund in Albania were lost as a result of looting and civil disorder in the country, and damp or mildew. In the end, RTÉ agreed to apologise over one issue, the segment dealing with the death of the lawyer.
Kosta Tribecka had been a whistleblower against alleged corruption in the export of Communist-era ammunition from Albania. His bloodied remains were found on a dirt road in 2008. Mr Ganley denied having a close business relationship with Mr Tribecka.
He told the Irish Independent the only connection was that his business had a contract with a bank and that Mr Tribecka had been subcontracted by another contractor who provided technology and expertise to the same bank.
In its apology, the broadcaster said: "RTÉ accepts unreservedly - as stated on the programme - that the death of Mr Tribecka was wholly unrelated to Mr Ganley or any business related to him. RTÉ apologises to Mr Ganley for any hurt or distress that may have been caused."
In his lawsuit, Mr Ganley had also claimed the programme used words or innuendo which meant he had falsely claimed to be a paid adviser to the Latvian government and had links to organised crime.
He also alleged it falsely suggested he caused the Anglo Adriatic Investment Fund to lose the life savings of thousands of Albanian pensioners and was covertly working for the CIA "and/or an ill-defined group known as Neocons". No reference was made to any of these issues in the RTÉ apology. Asked why he had not pursued these claims, Mr Ganley said he had made "a call" and decided to "move on".
"I am an experienced litigant. There is an apology, which I accept, and a cheque which is big, which I accept. I am a busy guy," he said.
Mr Ganley was also in the news this week after CNN reported the Trump administration was pressuring US Department of Defence officials to award Rivada a multi-billion dollar 5G network contract. While Rivada is interested in the contract, Mr Ganley insisted there was "zero truth" to the story. "It is just ridiculous," he said.
At the moment, he has no plans to return to politics, saying he is focussed on Rivada and glad he wasn't elected an MEP. While economies are suffering worldwide due to the pandemic, he said the wireless broadband industry had "come to the fore in a way it never previously has".
"I wanted to be able to bring the European reform argument that we were making, that was from a pro-European perspective, into the European Parliament. I didn't get the opportunity to do that. But what I did get the opportunity to do was to refocus all of my efforts entirely on my business and that was a much better use of my time for me and my family," he said.
