Restraint of Trade Enforcement in Victoria: When Post-Employment and Commercial Restraints Hold Up 

For many Victorian business owners, senior executives, and professionals, the real dispute begins after the employment or commercial relationship ends. A departing executive may start approaching former clients, a shareholder may launch a competing business, or confidential information may be used to undermine years of commercial investment. In these situations, the key question is whether restraint of trade enforcement in Victoria courts will uphold the clause or strike it down as unenforceable. 

Under Victorian law, restraints of trade are not automatically valid simply because they appear in a contract. Courts apply a strict reasonableness test to determine whether the restraint goes further than necessary to protect a legitimate protectable interest, such as confidential information, client relationships, or goodwill protection. The enforceability of a cascading restraint clause, the availability of an equitable injunction, and the commercial context of the agreement can all significantly affect the outcome. 

For high-value businesses and departing executives, understanding how Victorian courts approach restraint clauses is critical to managing risk, preserving commercial value, and responding quickly when disputes arise. 

When Are Restraint of Trade Clauses Enforceable in Victoria? 

In Victoria, restraint of trade clauses are governed primarily by common law principles rather than a single statute. Courts begin from the position that restraints are presumed unenforceable unless the party seeking to enforce them can prove they are reasonable and necessary to protect a legitimate protectable interest. This principle underpins most restraint of trade enforcement disputes involving departing executives, shareholders, professionals, and business owners. 

The leading authority is Buckley v Tutty (1971) 125 CLR 353, where the High Court confirmed that restraints limiting a person’s ability to work or conduct business are contrary to public policy unless they are necessary to protect another party’s commercial interests. Importantly, the law does not permit restraints designed merely to stop ordinary competition. Courts recognise protectable interests such as confidential information, customer relationships, trade connections, and goodwill protection. 

Victorian courts apply a strict reasonableness test when assessing enforceability. This involves examining the duration of the restraint, its geographic scope, and the activities being restricted. A narrowly tailored six-month non-solicitation clause may be enforceable, while a broad nationwide restraint lasting several years may fail if it exceeds what is commercially necessary. 

In Just Group Ltd v Peck [2016] VSCA 334, the Victorian Court of Appeal refused to enforce parts of a restraint clause against a former executive because the employer could not justify the breadth of the restrictions at the time the contract was signed. The case reinforced that reasonableness is assessed prospectively, not after the dispute arises. 

Many modern agreements include a cascading restraint clause, which provides alternative time periods or geographic limits. Courts may enforce the narrowest reasonable version while severing unenforceable parts. Where urgent commercial harm is threatened, businesses frequently seek an equitable injunction to restrain conduct pending trial, particularly in disputes involving confidential information, client poaching, or breaches connected to director duties. 

How Do Victorian Courts Decide Whether a Restraint of Trade Is Enforceable? 

What Commercial Interests Will Courts Protect? 

Victorian courts will only enforce restraints that protect a genuine, legitimate, protectable interest. This commonly includes confidential business information, trade secrets, key client relationships, pricing structures, strategic plans, and established customer goodwill. Courts are willing to uphold restraints involving senior executives, directors, equity partners, and business sellers because those individuals often possess commercially sensitive information capable of causing significant competitive harm. 

By contrast, courts will not enforce restraint clauses simply to prevent ordinary market competition or to punish a departing employee. An employer must demonstrate a real commercial risk that justifies restricting another party’s ability to work or operate a business. 

How Important Is the Reasonableness Test? 

The reasonableness test is central to every restraint of trade enforcement dispute. Courts assess whether the restraint goes further than reasonably necessary to protect the relevant business interest. This analysis focuses on three key areas: 

• the duration of the restraint;  

• the geographic area covered; and  

• the scope of prohibited activities.  

A narrowly drafted clause tailored to client solicitation or confidential information is far more likely to be enforceable than a blanket prohibition on working within an industry. Victorian courts also examine the employee’s seniority, bargaining power, and access to commercially valuable information at the time the agreement was entered into. 

Do Cascading Restraint Clauses Improve Enforceability? 

A properly drafted cascading restraint clause can significantly improve enforceability prospects. These clauses contain multiple alternative restraints with varying time periods, geographic limits, or activity restrictions. If a court considers one version too broad, it may sever the unreasonable portion and enforce a narrower alternative. 

However, cascading clauses are not automatically valid. Courts will still examine whether each alternative is commercially justified and drafted with sufficient precision. Poorly structured clauses may still fail entirely if they appear artificial or excessively broad. 

What Evidence Do Courts Require in Restraint Proceedings? 

Courts expect clear evidence showing both the existence of a protectable interest and the risk of harm. Businesses commonly rely on employment contracts, shareholder agreements, client movement records, confidential communications, forensic IT evidence, and evidence of solicitation activity. 

Where urgent harm is alleged, parties frequently seek interlocutory injunctions, urgent court applications, or interim relief to prevent ongoing breaches before trial. Courts are more likely to grant urgent relief where there is evidence of misuse of confidential information or conduct linked to breaches discussed in our article on breach of confidence claims and disputes. 

When Will a Court Refuse to Enforce a Restraint? 

Victorian courts regularly refuse enforcement where restraints are drafted too broadly or where the employer cannot justify the restriction commercially. Delays in taking legal action may also weaken applications for urgent relief. Courts are particularly cautious where restraints would unreasonably prevent a person from earning a livelihood or operating within their established profession. 

What Types of Restraint of Trade Disputes Commonly Reach Victorian Courts? 

Disputes involving restraint of trade enforcement claims commonly arise after senior employees, directors, shareholders, or business partners leave an organisation and begin competing activities shortly afterwards. In many cases, commercial damage occurs quickly, which is why these matters frequently involve urgent legal applications and immediate strategic advice. 

One of the most common disputes involves departing executives soliciting clients or staff after resignation. Businesses often discover that key customers have moved to a competitor within weeks of an executive’s departure, sometimes alongside coordinated staff exits. In these matters, courts closely examine whether the individual had substantial influence over client relationships and whether the restraint protects a genuine legitimate protectable interest rather than simply restricting competition. 

Another recurring issue arises during business sales and shareholder exits. Vendors who sell a business for substantial value are often restrained from establishing competing operations nearby or targeting former clients. Courts are more willing to enforce broader restraints in sale-of-business disputes because the purchaser has paid for goodwill protection as part of the transaction. These disputes frequently intersect with obligations relating to director duties, shareholder conduct, and misuse of confidential commercial information. 

Professional services industries also generate significant restraint litigation. Accounting firms, financial advisory businesses, medical practices, recruitment agencies, and legal services providers regularly face disputes involving client databases, referral networks, and confidential pricing structures. In many of these matters, the practical dispute is not whether the former employee can continue working, but whether they can actively approach former clients or use commercially sensitive information obtained during employment. 

Urgent injunction applications are particularly common where electronic information is involved. Businesses increasingly rely on forensic investigations showing mass downloads, transfers of confidential files, or unusual access activity before resignation. These matters often proceed alongside claims involving breach of confidence and applications for urgent interlocutory relief designed to prevent further commercial harm before trial. 

From a practical perspective, timing is critical. Delayed enforcement action can undermine the strength of a restraint claim, particularly where client relationships or confidential information have already been compromised. Early legal advice often determines whether the dispute can be contained commercially or escalates into urgent Supreme Court litigation. 

What Should Businesses and Executives Do Before Enforcing or Challenging a Restraint of Trade? 

In restraint of trade enforcement disputes, the strength of the evidence often determines the outcome before a final hearing ever occurs. Businesses seeking enforcement should move quickly to preserve evidence of client solicitation, confidential information misuse, staff poaching, or suspicious electronic activity. Courts are far more willing to grant urgent relief where there is clear contemporaneous evidence showing a real risk of commercial harm. 

For employers and business owners, restraint clauses should be reviewed well before a dispute arises. Courts closely scrutinise whether the restraint is proportionate to the role, industry, and commercial interest being protected. Overly broad clauses can weaken an otherwise legitimate claim. A carefully drafted cascading restraint clause supported by clear contractual obligations and confidentiality protections is more effective than relying on aggressive blanket restraints. 

For departing executives and professionals, it is critical to assess the enforceability of the restraint before taking steps that may trigger litigation. Accessing client databases, transferring files, contacting former clients prematurely, or coordinating staff departures can significantly increase the likelihood of urgent court proceedings and claims for an equitable injunction. 

Strategically, parties should also consider the commercial realities of enforcement. Even where a restraint may succeed under the reasonableness test, litigation can be costly, time-sensitive, and commercially disruptive. Early legal advice often allows disputes to be resolved through negotiated undertakings, limited restraint periods, or carefully structured exit arrangements that protect both ongoing business interests and professional mobility.
