In what circumstances will a court dismiss an action for wrongful dismissal?

In Scott v. Lauber, case number 4:05-cv-04355-PJH (PR), the district court dismissed the case on April 13, 2006, without prejudice, as duplicative and it is clear from the order that it was filed as a result of the erroneous dismissal of the earlier action and not based on abusive litigation tactics. (Ex. 6.)

In Scott v. Lauber, case number 4:05-cv-00111-PJH, the district court dismissed the action, without prejudice, on July 3, 2008, for failure to keep the court apprised of a current address, following returned mail in the case. (Ex. 5.)
