What is the difference between arbitration and expert determination?

Arbitration and expert determination are different contractual procedures for resolving disagreements. Arbitration authorises a tribunal to adjudicate defined disputes and issue an award subject to applicable arbitration legislation. Expert determination ordinarily appoints a specialist to decide a specified technical, valuation or accounting question under the contract, often without conducting an adversarial legal hearing. The label used by the parties is relevant, but the actual powers, procedure and intended legal effect are decisive.

In Pakistan, domestic arbitration is governed principally by the Arbitration Act, 1940. A process described as expert determination does not automatically fall under that Act, although a poorly drafted clause can generate disagreement about whether the parties intended arbitration. The distinction matters for court appointments, challenge grounds, interim relief and enforcement.

Purpose of the two processes

Arbitration is suited to legal disputes involving contractual entitlement, breach, evidence, compensation and interpretation.

Expert determination is often used for a defined specialist question, such as fair market value of shares, engineering quantities or calculation of completion accounts.

A contract may use both: an expert determines technical inputs, while an arbitrator resolves the broader legal dispute.

The source of authority

An arbitrator derives authority from a legally effective arbitration agreement and applicable law.

An expert derives authority from the contract appointing or providing for appointment of that expert.

A person cannot simply declare themselves an arbitrator or expert because one party asks them to produce a report.

Arbitration under the 1940 Act

The Act regulates domestic appointments, references, awards and court supervision within its scope.

Sections 8 and 20 can assist with appointments or reference in appropriate circumstances. Sections 30–33 address specified challenges.

The parties should ensure the dispute clause identifies a workable process rather than merely saying differences "will be resolved by a mutually acceptable person."

Technical valuation example

Shareholders may agree that an independent chartered accountant will determine the fair market value of shares using an agreed methodology.

The expert's task may involve accounts and valuation assumptions, not whether a shareholder committed oppression or breached statutory duties.

Where the dispute is over legal validity of the transfer, a separate judicial or arbitral process may remain necessary.

Procedure and hearings

Arbitrators ordinarily must provide a fair opportunity for parties to present their cases under the governing framework.

Experts may use their own knowledge and investigation within the contractual mandate, subject to any required fair procedure.

The parties should specify whether submissions, meetings, disclosure of working papers or responses to a draft determination are permitted.

Independence and conflicts

Both processes require care over conflicts, but appointment documents can provide different disclosure and challenge mechanisms.

A supplier's own engineer may be inappropriate as an independent expert determining that supplier's disputed performance, unless parties knowingly agreed otherwise.

Document qualifications, fee arrangements and existing relationships before appointment.

Binding effect

An arbitral award can have the legal consequences prescribed by the Arbitration Act and applicable enforcement law.

An expert's decision may be contractually binding as to the specified question, but its enforcement ordinarily follows the legal mechanism applicable to contractual obligations, subject to judicial principles.

Do not call an expert certificate an arbitral award merely to invoke statutory execution procedures.

Challenge grounds

A domestic arbitral award may be challenged under section 30 and related provisions.

An expert determination may be contested on contractual grounds such as acting outside mandate, identified material error within the agreed standard or fraud, depending on law and terms.

The two processes do not necessarily share identical limitation rules or court-review standards.

Distinguish errors in the question

A valuation expert instructed to value shares as of 31 December should not substitute a date of personal preference.

An arbitrator deciding a damages dispute may need to interpret the contract and resolve contested legal responsibility.

A party dissatisfied with the price determined cannot necessarily ask a court to repeat the valuation without a recognised ground.

Appointing authority

A commercial contract should identify who appoints the expert, when, and what happens if parties fail to agree.

Professional bodies or institutions may act as appointing authorities if properly designated.

Arbitration clauses likewise require a workable tribunal appointment process, but statutory default mechanisms may differ.

Costs and duration

Expert determination can be faster and narrower for technical issues, with costs associated with the specialist's investigation.

Arbitration may involve pleadings, evidence, hearings and more extensive legal expenses.

The choice should reflect dispute complexity rather than assume expert determination is always cheaper or arbitration always superior.

Confidentiality and disclosure

Contractual confidentiality arrangements may govern reports and submissions in either process.

An expert's calculations may involve confidential pricing or commercial records, so the appointment should specify how information is handled.

An arbitral tribunal can also deal with confidentiality under the agreement and applicable rules.

Using both in a construction contract

A contract may require an engineer to measure quantities and determine monthly valuations, with legal disputes referred to a dispute board or arbitration.

Not every engineer's certificate is an arbitral award. The engineer's contractual function and available challenge route must be identified.

A contractor should avoid missing contractual notices while waiting for a separate technical valuation.

Accounting completion dispute

A buyer acquires a company subject to post-closing adjustment of net working capital.

An independent accountant can calculate disputed figures, while arbitration deals with alleged fraudulent warranties.

Clear division of scope prevents the accountant from inadvertently adjudicating questions reserved for the tribunal.

Public sector issues

A government contract may have statutory constraints on who can decide final payment obligations or approve settlement.

An expert appointment does not necessarily override mandatory procurement and public finance rules.

The public authority should ensure the expert's role is within its lawful powers and contractual approvals.

Drafting recommendations

Define the issue, standard, evidence, decision deadline, expert qualifications, allocation of fees, binding effect and permitted challenges.

If arbitration follows, state whether the expert's finding is final on technical facts or can be reconsidered under defined circumstances.

Avoid clauses that use the terms arbitration, expert and mediation interchangeably.

Opinion and recommended course

Arbitration adjudicates disputes under a recognised legal framework; expert determination resolves a contractually defined specialist question. Their binding effect, procedure and review differ.

Choose expert determination for narrow technical or valuation matters and arbitration where adjudication of legal claims is required. Draft the scope and interface carefully to avoid competing or unenforceable decisions.
