The Bush administration was hoping to have more time to figure out how to roll back rules approved by the Clinton administration to ban road-building and logging on a third of the country’s national forests — but a federal judge threw a kink into that plan yesterday. The judge denied the administration’s plea to delay a hearing on the ban that is scheduled for next week. The hearing will address the state of Idaho’s request for an injunction on the ban; the delay sought by the administration would have effectively granted the state its request. Now the administration has only until next week to figure out its position on the roadless rules.
