In Gregg v. Superior Court (1987) 194 Cal. App. 3d 134, the court acknowledged that "the principle of priority based on comity applies most strongly where the federal and state court actions are in rem or quasi in rem." (Id. at p. 137.) However, in the next paragraph, the court recognized the role of comity in in personam actions: "The California authorities discussing priority as between federal and state in personam actions conclude that an application for a stay is addressed to the 'sound discretion' of the trial court ." (Ibid.)
