Ciaran O'Reilly was appointed chief execuitve of Pulse Marketing's Dublin office in 2002. It emerged late last year that he and the Dublin office's creative director, Brendan O'Flaherty, had helped establish a new online advertising agency, Brando.

Pulse Marketing obtained an injunction 10 days ago restraining O'Reilly and O'Flaherty from contacting any of its clients, suppliers, contractors or employees and from using any information relating to the company. That injunction was lifted on Friday by the High Court which will detail its reasons for the removal this week. The High Court has also issued an order against O'Reilly requesting him to return all files owned by or relating to his former employer.

Pulse Marketing, whose clients have included Rabobank and Lucozade Sport, alleged in court that O'Reilly informed his codirectors last year that he had secured a tenant for vacant space at Pulse Marketing's premises in Dublin.

The company additionally claimed in court that O'Reilly notified directors that he had only been able to secure rent for the space at 20% less than the price paid by the previous tenant. Pulse Marketing alleged that O'Reilly failed to disclose at the time that he was a secretary and director of the new tenant, the Brando agency.
