(Reuters) – Google Inc on Thursday reversed its decision to remove several links to stories in Britains Guardian newspaper, underscoring the difficulty the search engine is having implementing Europes right to be forgotten ruling. The Guardian protested the removal of its stories describing how a soccer referee lied about reversing a penalty decision. It was unclear who asked Google to remove the stories. Separately, Google has not restored links to a BBC article that described how former Merrill Lynch Chief Executive Officer E. Stanley ONeal was ousted after the investment bank racked up billions of dollars in losses.
