The binding legal principles are: (1) In malicious prosecution, malice can be established through express malice (spite/ill-will), implied malice (indirect/improper motive), or dolus eventualis (reckless disregard for truth). (2) A plaintiff may elect to sue private instigators of prosecution without joining the State prosecuting authorities. (3) Going beyond merely reporting a crime to actively participating in arrest, detention and prosecution demonstrates instigation. (4) Prosecution lacks reasonable and probable cause where only minimal evidence links the accused, the accused has no means to commit the alleged crime, and the prosecution's own evidence reveals other culprits. (5) Resuscitating withdrawn charges without new evidence and with improper motives constitutes malicious prosecution. (6) In defamation, once defamatory matter is published, animus injuriandi is presumed and the defendant bears the onus to establish a defence. (7) The defence of qualified privilege fails where the defendant publishes statements without knowledge of their truth, acting recklessly as to their veracity. (8) A letter addressed to a person in their official capacity may be found to defame them personally where the context indicates the imputations relate to their personal conduct. (9) Special damages require proof of actual loss with supporting evidence; where such evidence is within the plaintiff's power but not produced, the defendant is absolved. (10) General damages for malicious prosecution and defamation are assessed considering the nature of the imputation, extent of publication, status of parties, probable consequences, presence or absence of malice, and absence of apology.
