In contentious Construction Litigation and Arbitration, Expert Witnesses are employed to assist the Court or Arbitrator with matters that fall outside the Tribunal’s area of professional expertise.

The Expert Witness provides the Judge or Arbitrator with opinion evidence based on his or her particular expertise and experience in his or her chosen area of professional practice and must be wholly independent of the Parties and impartial in the matter in dispute. An Expert Witness has no financial or other interest in the outcome of the dispute despite being retained by one of the Parties to give evidence and gives his or her honestly held opinion based on his or her appreciation and understanding of the facts and issues in dispute. Thus, the Expert’s duty is to the Tribunal and not to his or her Client.

Not all experts prove to be good expert witnesses as some can break down under cross-examination. A good Expert Witness will not only possess the qualities of an expert but who will prove to be an expert communicator, whose judgment is sound and who is comfortable with his or her report and testimony and who can deliver a wholly objective opinion that will be fully supported and which will be of assistance to the Court or Tribunal. In circumstances where new information comes to light then the Expert Witness will need to be able to deal with these changing circumstances and respond appropriately.

Appointments to act as an Independent Expert Witness are made by Solicitors and the costs involved represent part of the Legal Costs of any proceedings however, despite this, the payment terms and conditions of appointment are normally agreed with the Client directly.

Conciliation is a confidential process that is similar to Mediation wherein the Parties appoint an independent and impartial third Party (The Conciliator) who seeks to facilitate a settlement between the Parties through the skillful identification of the strengths and weaknesses of the Parties respective positions. A good Conciliator will be professionally qualified person with a breadth and depth of experience and will have a proper understanding of the technical, contractual, commercial and legal issues at play in any dispute.

He or she will be an expert communicator and capable of exploring potential solutions to the dispute. In Construction Conciliations it is usual to have plenary sessions wherein both Parties present their argument before the Conciliator and the other Party usually without interruption but this depends on the style adopted by the Conciliator who is master of the procedure.

In addition, the Conciliator will have private caucus meetings with each Party in separate rooms where he or she will test the Party’s argument in private and endeavor to lower tensions and expectations. If the difference between the Parties respective positions is not too great then a negotiated settlement may be achievable, which will become final and binding upon the Parties. If a settlement is not possible, then the proceedings will be adjourned and the Conciliator will retire to make his recommendation to the Parties.
The recommendation will be in a written format and if not dissented from by either Party within a specified period of time, normally 10 working days then the recommendation becomes final and binding.

Conciliation is widely employed In the Irish Construction Industry with all Standard Forms of Contract requiring the Parties to endeavor to resolve their differences through dialogue with the assistance of an Expert.

Under the Public Works Forms of Contract, Conciliation adopts a two stage approach. The first stage is identical to traditional Conciliation wherein the Conciliator explores ways of reaching a mutually acceptable agreement between the Parties. If this fails, then the Conciliator is obligated to issue a written recommendation based upon the rights and obligations of the Parties under the Contract. If this recommendation is not rejected within 45 calendar days then it becomes binding upon the Parties. This second stage is more akin to adjudication and differs from the Conciliation Procedures adopted by the Royal Institute of Architects Ireland and Engineer’s Ireland wherein the Conciliator may elect to recommend a sum of money that he or she considers is appropriate in all the circumstances and which the Parties can live with.
