The binding legal principles established are: (1) A conviction for public violence can properly be based on the evidence of a single credible eyewitness, particularly where that witness was familiar with the accused, observed events at close proximity, interacted directly with the accused during the incident, and provided detailed identifying information. (2) Where an accused fails to cross-examine a witness on crucial aspects of the witness's evidence that go to the heart of the charge (such as placing barricades on roads and assisting in damaging state property), such failure may be taken as acceptance of that evidence. (3) Minor contradictions in witness testimony that do not go to the root of the State's case are insufficient to undermine credibility or warrant acquittal. (4) While citizens have a constitutional right to publicly express discontent and demonstrate, this right must be exercised without interfering with other citizens' constitutional rights to freedom of movement, privacy, safety of person and property. (5) Custodial deterrent sentences are appropriate for public violence offences that create serious risk to public safety and property, even where no actual harm eventuated, particularly where conduct involved blocking major roadways and creating potential for violent escalation. (6) An appellate court will not interfere with a sentence imposed by a lower court unless it is shown that the lower court's discretion was not judiciously exercised - it is insufficient merely to argue that an alternative sentence (such as community service) could have been imposed.
