In Ireland, he'd have found a solicitor eager to take his case, a doctor and specialist consultant to confirm his injuries and a barrister to argue his case in the Circuit court (district court settlements too small).
The small business defending the case would have had to hire a legal team and wait 3 years for the case to go to court, despite having cctv evidence. Meanwhile their insurance premium would have jumped upon the first renewal.
The insurance company would have had to hire an investigator to follow the injured victim for a while and see if his injuries were affecting his life as claimed. They may also have tried to settle the case on the steps of the court.
So after wasting court time at the expense of the taxpayer, the Judge would have taken one look at the CCTV and thrown out the case and awarded costs against the claimant, wondering how the case got this far. The claimant would have walked free out of the court and as he was probably incapable of paying the fees, he wouldn't be pursued for them. The Gardai wouldn't even think of calling him in for a chat.
The case would have made the Indo and perhaps The Last Word where a representative for the Law Society would piously state that the result in this case shows that the system works and there's no need for any reform.
The small business owner is left with higher premiums as they are the new normal for his business. And he also has a hefty legal bill to pay.
The 'house' always wins!
