Just a few dozen people attended the Smithfield Horse Fair in Dublin this morning.
The September Fair is usually one of the busiest of the year.
Members of the Revenue Commissioners, the Department of Social Protection, the DSPCA and gardaí operated a checkpoint at the entrance to Smithfield Square.
Dublin City Council meets tomorrow to discuss new by-laws to regulate the fair.
They include a requirement for traders to have public liability insurance of up to €6.4m, which traders say would be impossible for them to pay.
The plans would also require traders to have a licence and limit the fair to taking place twice a year in May and September.
