Unfair despite symmetry: court rules mandatory arbitration clauses may be unfair

Insights28 Apr 2026

The Federal Court decision in AghaeiRad v Plus500[1] is an important development in the application of the unfair contract terms regime, particularly in respect of dispute resolution clauses. It confirms that mandatory arbitration clauses under standard form contracts may be unfair where their practical effect is to prevent a party from accessing courts or participating in class actions, even where the clause is seemingly symmetrical and applies to both parties.

Key takeaways

  • In AghaeiRad, the Federal Court ruled a mandatory arbitration clause in a standard form User Agreement was void as an unfair contract term under section 12BF of the Australian Securities and Investments Commission Act 2001 (Cth) (ASIC Act). 

  • The relevant clause was found to be unfair notwithstanding it had been drafted symmetrically.

  • In an earlier case of Kaprik v Carnival[2], the fact that the relevant class action waiver clause was stated as being specifically for the benefit of the operator (and therefore asymmetrical) was an important factor in finding that clause to be unfair. 

  • AghaeiRad is therefore important as it confirms that mandatory arbitration under standard form contracts may be unfair where their practical effect is to prevent a party from accessing courts or participating in class actions, even where the clause is seemingly symmetrical and applies to both parties. 

  • The case also opens the door for courts to hold that other symmetrical terms cause a significant imbalance where there is an asymmetric practical effect. When drafting standard form contracts businesses cannot assume that just because a clause has been drafted symmetrically that it will not be an unfair term

This decision is an important development in the application of the unfair contract terms regime to dispute resolution clauses.

In an earlier case, Dialogue Consulting Pty Ltd v Instagram, Inc[3], the relevant clause requiring the parties to use arbitration to resolve disputes was held not to be unfair (although that case is distinguishable on its facts). While in the case of Kaprik v Carnival[4], the fact that the relevant class action waiver clause was stated as being specifically for the benefit of the operator (and therefore asymmetrical) was an important factor in finding that clause to be unfair. 

This case is therefore important as it confirms that mandatory arbitration under standard form contracts may be unfair where their practical effect is to prevent a party from accessing courts or participating in class actions, even where the clause is seemingly symmetrical and applies to both parties. Further, the case opens the door for courts to hold that other symmetrical terms cause a significant imbalance where there is an asymmetric practical effect.

Clauses in standard form contracts that require the parties to use arbitration will not always be unfair (as Dialogue v Instagram shows). However, businesses that include dispute resolution clauses in standard form contracts should carefully consider whether such clauses can withstand scrutiny under the unfair contract terms provisions of the ASIC Act and the Australian Consumer Law, particularly if the clause requires the parties use arbitration or seeks to prevent a party from participating in any class action.

Further, when drafting standard form contracts businesses cannot assume that just because a clause has been drafted symmetrically that it will not be an unfair term. Businesses will need to carefully consider whether the term causes a significant imbalance in the parties’ rights and obligations.
