BOSTON (Reuters) - The granddaughter of Viacom Inc's <VIAB.O> controlling shareholder Sumner Redstone has agreed to let a Massachusetts court dismiss claims brought by former company leaders, a step that will help end a battle over the fate of the media empire.

Lawyers for Keryn Redstone said at a Massachusetts court hearing on Friday they have also agreed to mediate remaining parts of her family dispute and that she will have an in-person meeting with her 93-year-old grandfather.
