Tyr LLP is founded

Jim Bunting, Sean Campbell and Jim Doris have announced that they are leaving Davies, Ward, Phillips & Vineberg LLP to found a new litigation firm, Tyr LLP. The three former Davies partners have over 55 years of experience litigating at one of Canada's top litigation firms.

Although it is bittersweet to leave friends and colleagues at Davies, the three partners are enthusiastic about their new venture. The name of the firm, Tyr (pronounced like the word “tier”), is derived from an ancient Norse war god, who was responsible for upholding law and justice. Tyr was known for his bravery and, by legend, sacrificed one of his arms to uphold the law and protect his people. The decision to name the firm Tyr, rather than using the names of the firm's founding parties, reflects the firm's collaborative and team oriented approach, as well as the firm's desire to grow from the strong foundation provided by its founding partners.

Semenya's battle against the IAAF has become a rallying cry for human-rights activists

When Caster Semenya crossed the finish line to win the gold medal in the 800 metres at the 2016 Olympic Games in Rio, she didn't get the customary hugs and handshakes from her beaten rivals. Instead those trailing in her wake, including Canada's Melissa Bishop, who came fourth, embraced each other and coolly stood aside while Semenya awkwardly reached out. "Everyone can see that it's two separate races, so there is nothing I can do,” said Britain's Lynsey Sharp, who finished sixth. That paled in comparison to what Italy's Elisa Cusma once said after being beaten by Semenya: “These kinds of people should not run with us. For me, she is not a woman. She is a man.”
