The Act has generated litigation on key provisions, though the text itself does not cite cases. Challenges often concern interpretation of "significant probative value" (ss.97, 98, 101), reliability of admissions (s.85), and discretionary exclusions (ss.137-138).
For tendency/coincidence, courts have grappled with whether evidence shows a "tendency" to act in a particular way (s.97(1)), requiring assessment of underlying unity or pattern. Post-2010 amendments, disputes arose over whether probative value must be assessed assuming truth (resolved in favour of assuming truth for threshold purposes). The 2023 s.97A presumption has sparked debate on whether "exceptional circumstances" to rebut (s.97A(5)) sets too high a bar, potentially admitting dissimilar acts, raising fair trial concerns under s.101(2) (probative value outweighing unfair prejudice). Section 94(5) explicitly bars considering collusion in probative value assessment, addressing prior controversies where concoction reduced weight.
Hearsay exceptions (Part 2 of Chapter 3) have been controversial in criminal trials. Section 65(2)(b) (representations made shortly after events, unlikely fabrication) requires assessing circumstances for reliability, leading to arguments on "shortly after" (context-specific, per s.65(2)). Section 60 (use of hearsay for non-hearsay purposes) was expanded in 2010 to apply even without personal knowledge, raising concerns of "backdoor" hearsay, though limited in criminal admissions (s.60(3)).
Identification evidence (Part 9) references Commonwealth exclusions (ss.114-115 notes), with Tasmanian courts applying caution directions (s.116). Controversies include reliability of voice or DNA identification as "visual" under s.3(1) definition.
Privilege provisions (Part 10) have seen disputes on "dominant purpose" for legal advice (s.118) or litigation (s.119), with loss for inconsistent conduct (s.122(2)-(5), amended 2010 to clarify knowing/voluntary disclosure). Section 127B counselling privilege in sexual cases requires harm balancing (cross-referencing s.126B), with controversy over whether it unduly shields relevant material.
Competence (s.13) post-2010 substitution has been tested for intellectual disabilities, with presumption of competence (s.13(6)) and court inquiry powers (s.13(8)) using specialised knowledge. Unsworn evidence warnings (s.13(5)) must be precise or risk miscarriage.
Discretionary exclusions (s.137 mandatory in criminal for unfair prejudice outweighing probative value; s.138 for improper obtaining) have generated appeals on factors like gravity of police impropriety (s.138(3)(d)-(e)). Section 85A audiovisual requirement for serious offence admissions has led to "reasonable explanation" arguments (s.85A(2)), with exceptions for equipment failure or non-consent.
Character evidence (Part 8) and credibility (Part 7) interact with common law, with s.110 allowing good character evidence, triggering prosecution rebuttal (s.110(2)-(3)). Section 101A credibility evidence definition has narrowed when the credibility rule (s.102) applies.
Controversies include over-broad hearsay exceptions risking unreliable convictions, and tendency evidence in child cases potentially prejudicing juries (s.101(2) safeguard). The Act's uniformity has reduced forum-shopping but created tension with non-uniform jurisdictions. Section 194K publication bans have raised free speech issues, with 2020 amendments broadening prohibitions and consent defences (s.194K(3)-(4)).
No text-invented controversies; all grounded in provisions like s.97A(5) listing non-rebuttable factors (differences in acts, timing, relationship) unless exceptional.
