How should evidence in claims be presented according to Queensland laws?

In Queensland, the presentation of evidence in claims is primarily done orally, particularly during court proceedings, and through affidavits for applications. This approach aligns with the adversarial system of justice common in Australian courts, where oral evidence allows witnesses to convey their testimonies directly, facilitating immediate interaction for cross-examinations and verifications of credibility.

Affidavits serve as a vital tool for presenting evidence in applications, providing a formal written statement that is sworn to be true, thus maintaining the integrity of the information presented to the court. This dual method of evidence presentation enhances the clarity and effectiveness of court proceedings by allowing both written records and dynamic oral testimony.

The other options do not capture the requirement for both oral and affidavit evidence. Relying solely on written affidavits would limit the interactive aspect of the judicial process. Using compiled summaries of evidence might overlook the detailed and personal nature of witness testimonies that is essential in many cases. Lastly, mandating all evidence to be submitted via email would not conform to court procedural rules regarding proper presentation and transmission of evidence. Thus, the correct choice encompasses the necessary combination of oral and affidavit-based evidence, as recognized by Queensland law.
