WestlawNext recently improved their Keycite citator product by introducing a new signal flag.
According to West, this lovely striped friend:
"will warn that a case has been appealed to the U.S. Court of Appeals or the U.S. Supreme Court. This is neutral and not meant to be negative.
It will drop-off when the decision has reached the reviewing court.
It is fully integrated in Dockets and Alerts. "
