Extraterritorial mischief: Internet regulation by trial court

One of the chronic issues of internet law is extraterritoriality: When can a court in one country control content elsewhere? Last week, the Canadian Supreme Court considerably increased the risk of a major clash over this issue. In a recent decision (Google Inc. v. Equustek Solutions Inc), the court held that a Canadian trial court acted properly in ordering Google to hide certain content from users anywhere in the world. Unless this principle is promptly restrained, it is liable to do a great deal of mischief.
