By Leah Schnurr and Mica Rosenberg OTTAWA/NEW YORK (Reuters) – Canada’s top court ruled on Friday that the World Bank did not need to turn over documents sought in a case against former employees of SNC-Lavalin accused of bribery, finding the international organization had immunity from the request. The case has been closely watched given its implications for how the World Bank investigates corruption and its ability to protect whistleblowers. The Supreme Court of Canada overturned a lower court order from 2014 that said the World Bank should release its investigative files for judicial review that could be relevant to the defense.
