These excerpts from the judge in Ezra Levant's most recent defamation loss (2014) still ring true: 

"The numerous errors made by the defendant [Levant] also speak to the question of malice. Although he agreed in cross-examination that it was important to publish accurate facts, he did little or no fact-checking regarding the posts complained of, either before or after their publication. Nor did he accurately report what was taking place at the hearing. And, with one exception, when he learned that he got his facts wrong, he made no corrections." 

"I find that the defendant’s [Levant's] dominant motive in these blog posts was ill-will, and that his repeated failure to take even basic steps to check his facts showed a reckless disregard for the truth."
