UN human rights commissioner Louise Arbour is stepping down June 30 after serving one four-year term. Ms. Arbour, a former Canadian supreme court justice, told reporters in Geneva that she wants to spend more time with her family. Ms. Arbour was the second high-ranking UN official to step down last week, following French UN peacekeeping chief Jean-Marie Guehenno's resignation on March 6. Ms. Arbour acknowledged that the criticism she has received over the years from countries like Zimbabwe, the U.S. and Israel has been hurtful, but that she is not quitting because of this pressure. She expects to return to Canada on July 1.
