Hi there. Based on the information you provided, it appears that you are asking whether you can sue the public transport service provider that issued you with an infringement notice for fare evasion. Fines for fare evasion are issued to persons who travel on public transport without a valid ticket or valid proof of concession. In Queensland, fines are issued by authorised officers, including TransLink Senior Network Officers and police officers.

An authorised officer has the power to issue a fine if they believe a person has committed a public transport offence, such as travelling without a valid ticket. The passenger has the right to challenge the fine in court by pleading not guilty. Just because a you are found not guilty of a public transport offence or have no case to answer, does not mean you have an automatic right to sue the transport service provider or the authorised officer who issued you with a fine. In fact, there are laws in Queensland that ensure an authorised officer cannot be personally sued for their conduct on the job, provided they have acted honestly and without negligence (see the Transport Operations (Passenger Transport) Act 1994 (Qld)).

As a general rule, to sue a person or organisation, you need to have a cause of action. This means that you need to have a recognised legal basis for your claim. From the information you provided, the legal basis for your claim against the transport provider is not clear. If the transport provider (or authorised officer) acted negligently or fraudulently in issuing you the fine for fare evasion, then you may be able to sue them for negligence. However, a negligence claim can be very difficult to establish and you would need to prove that you have suffered harm or loss as a result of the incident.
