identity of causes of action

The same cause of action in two cases, an essential element of res judicata. 30A Am J Rev ed Judgm § 363. Two actions asserting the same rights, demanding the same relief, and founded on the same facts. Anno: 31 ALR2d 446 § 3. Not necessarily a matter of identity of subject matter. Creek v Laski, 248 Mich 425, 227 NW 817, 65 ALR 1113. Tested generally according to whether or not the same evidence would sustain both causes of action. 30A Am J Rev ed Judgm § 365. A prerequisite to a plea of abatement on the ground of prior action pending; a term characterizing two actions of the same character, for the same cause and relief, and in all respects identical. McAllister v McAllister, 147 Fla 647, 3 So 2d 351. Actions of the same character, for the same cause and relief, and in all respects identical, or actions having the same subject matter, although not demanding exactly the same specific relief. 1 Am J2d Abat & R § 26. Identity exists irrespective of whether the same specific relief be demanded, if the subject matter of both actions is the same, the ultimate inquiry being whether a judgment in the one action such being rendered first, will be conclusive on the parties with respect to the matters involved in the second. 1 Am J2d Abat & R § 26.
