On a motion to reconsider a previous motion seeking to add Defendant's wife as co-defendant that was denied, the Court found the evidence presented did not constitute "good cause" to amend the scheduling order as the moving party knew or could have known, with the "exercise of due diligence," the facts prior to the deadline for filing a motion to amend the scheduling order. Furthermore, no cause existed under 60(b)(1) to reconsider the prior order as neglient mistake or carelessness does not provide a basis for relief from a judgment or order.
