Gemini Response: This is a critical procedural point in Australian courts. If a person is called as a witness and refuses to take the required oath or make an affirmation that they will tell the truth, they will generally not be permitted to give evidence in the proceeding.

Here is a breakdown of what happens:

* Requirement: Under the Uniform Evidence Acts (which apply in Federal courts and most Australian states/territories), a witness must either take an oath (a promise with religious significance) or make an affirmation (a solemn, non-religious promise) before giving sworn evidence. Both options carry the same legal weight and a witness has the right to choose which one they prefer. * The Choice: The court officer will ask the witness which they prefer. The refusal must be a refusal of both options. A refusal to take an oath (due to lack of religious belief, for example) is immediately addressed by offering the affirmation.

1. Refusal to Give Evidence A witness who refuses to be sworn or to affirm their evidence is not allowed to give “sworn evidence”. In most cases, this means their evidence simply cannot be admitted into the trial.

2. Potential for Unsworn Evidence (Limited Circumstances) In some very limited situations, particularly concerning children or people with an intellectual impairment who are considered not to understand the nature of an oath or affirmation, the court may allow them to give unsworn evidence. However, for a fully capable adult who simply refuses both, this is unlikely to be an option, as the law requires a witness to be sworn or affirmed unless an exception applies.

3. Contempt of Court If the person refusing is a subpoenaed witness (meaning they are under a court order to attend and give evidence) and they persist in their refusal without a lawful excuse, they may be found to be in contempt of court.

• Subpoena Power: The court has the power to compel a witness to attend and give evidence. Refusing to comply with a legitimate order (like being sworn or affirmed to testify) can be seen as obstructing the court's process.
• Penalties: Contempt of court is a serious matter and can result in a fine or, in severe cases, imprisonment.

The law deliberately provides the choice between an oath and an affirmation to respect all beliefs (or lack thereof). Therefore, a person cannot generally claim a lawful excuse for refusing to testify based on their beliefs, as the non-religious affirmation option is available.

It's a moment in court procedure where someone who truly intends to tell the exact opposite of what they intended to say might commit a serious error—a real sliptun in judgment, though the legal system views a refusal to be sworn or affirmed as a deliberate refusal to participate in the court's process.

User Question: What is the difference between physiological truth and legal truth

Gemini Response: That's a fantastic question that highlights the fundamental tension between a court's formal process and the complexities of human reality.

The difference lies in the goal, method, and standard used to establish “truth.” While there isn't a single established legal term “physiological truth,” we can define it as Substantive Truth (what actually happened) versus Legal Truth (what the court finds happened).

This is the ultimate, objective, and factual truth of an event, independent of a judicial process. It is what 'really happened' in the world.

This is the truth that is formally declared by the judge or jury at the end of a trial. It is the necessary social and procedural finding that allows the system to resolve a dispute and apply the law.

The most crucial difference is that Legal Truth is a procedural finding, while Physiological/Substantive Truth is a reality statement.

The law explicitly prioritises the integrity of the process and rights (like the right to silence or protection from illegally obtained evidence) over an unconstrained search for the absolute truth.

For example: * A person may be physiologically guilty of a crime (they actually committed it). * However, if the prosecution fails to prove guilt beyond a reasonable doubt, the finding of Legal Truth is “Not Guilty.”

The legal system settles for a “best possible” approximation of the truth, achieved through a fair and formal process.

User Question: In an Australian court does a person that is Subpoenaed have the right to silence

Gemini Response: That is an excellent and crucial legal question, and the answer involves a key distinction in Australian law between an Accused/Defendant and a Witness under Subpoena.

In short: No, a witness under subpoena in an Australian court does not have the “right to silence” in the same absolute way an accused person does.

Instead of the right to silence, the witness is protected by the Privilege Against Self-Incrimination.

* Who it applies to: A person who is accused of an offence (the Defendant) in criminal proceedings. * What it means: The defendant has the absolute right not to give evidence at all in their trial, and no inference of guilt can generally be drawn from their silence (though there are some complex exceptions in NSW/VIC for serious indictable offences, and judicial comment is sometimes permitted). * Goal: To ensure the prosecution bears the entire burden of proving guilt beyond a reasonable doubt.

* Who it applies to: Any witness (including a subpoenaed witness) who is giving evidence. This witness is not the defendant in the current proceedings. * What it means: The witness must attend court and be sworn in (or affirm), and must answer all questions unless the answer to a specific question would tend to expose them to:

• Conviction for a criminal offence under Australian or foreign law; or
• Liability for a civil penalty.

In jurisdictions that use the Uniform Evidence Acts (Federal courts, NSW, Victoria, Tasmania, ACT, and NT), the procedure for a witness under subpoena is:

1. The Objection: If a question is asked and the witness believes their answer may incriminate them, they (or their lawyer) must formally object to answering it based on the privilege. 2. The Court Decides: The court stops the trial (often sending the jury out) and determines if there are reasonable grounds for the objection (i.e., a “real and appreciable danger” of self-incrimination, not just an imaginary one). 3. The Court's Power to Compel: If reasonable grounds exist, the court then has two options:

• Excuse the witness: Allow the witness not to answer the question.
• Compel the witness with a Certificate: If the court believes the evidence is necessary for the interests of justice, it can compel the witness to answer the question, but the court must grant a certificate (often called a “Section 128 Certificate”).

If the witness is compelled to answer and is given a certificate, the evidence they give cannot be used against them in any subsequent criminal or penalty proceedings (other than for perjury, or in a retrial for the same offence).

In summary: A subpoenaed witness is legally compelled to attend and generally answer questions. Their safeguard is not a blanket “right to silence,” but a conditional privilege to refuse to answer questions that incriminate them, which the court can override by offering an immunity certificate.
