MnDOT cites Martens for the proposition that a court may consider any document attached to any pleading on a motion to dismiss. MnDOT argues that, because the Hunter affidavit was attached to and referenced in its motion to dismiss, the district court properly considered the affidavit without converting the motion to one for summary judgment.
MnDOT’s reliance on Martens is misplaced. Rule 12.02 states:
If, on a motion asserting the defense that the pleading fails to state a claim upon which relief can be granted, matters outside the pleading are presented to and not excluded by the court, the motion shall be treated as one for summary judgment and disposed of as provided in Rule 56 *.
(Emphasis added.) Under a plain reading of this language, it is clear that the referenced “pleading” is the pleading that is the subject of the motion to dismiss. In
Martens, we limited “our review to the particular documents and oral statements referenced in the complaint,” the pleading that was the subject of the motion to dismiss.
616 N.W.2d at 739 n. 7. Here, the affidavits considered by the district court were not referenced in or a part of the pleading that was the subject of the motion to dismiss. Thus, having considered the affidavit, it was error for the district court not to have treated the motion as one for summary judgment under Rule 56.

On appeal from summary judgment, we consider (1) whether there are any genuine issues of material fact for trial and (2) whether the lower courts erred in their application of the law. Bank Midwest, Minnesota, Iowa, N.A. v. Lipetzky, 674 N.W.2d 176, 179 (Minn.2004). Although we review evidence in the light most favorable to the nonmoving party, summary judgment cannot be defeated with “unverified and conclusory allegations or by postulating evidence that might be developed at trial.” Funchess v. Cecil Newman Corp., 632 N.W.2d 666, 672 (Minn.2001).
Actions for inverse condemnation may appropriately be brought by writ of mandamus. Wolfram v. State by Burnquist, 246 Minn. 264, 267 n. 2, 74 N.W.2d 510, 512 n. 1 (1956). Mandamus is an extraordinary remedy, State v. Pero, 590 N.W.2d 319, 323 (Minn.1999), that is available only to compel a duty clearly required by law. Minn.Stat. § 586.01 (2002). In order to obtain mandamus relief, a petitioner must show that the defendant: (1) failed to perform an official duty clearly imposed by law, id.; (2) that, as a result, the petitioner suffered a public wrong specifically injurious to the petitioner, State ex rel. Coduti v. Hauser, 219 Minn. 297, 302, 17 N.W.2d 504, 507 (1945); and (3) that there is no other adequate legal remedy. Minn.Stat. § 586.02 (2002). Minnesota Statutes § 586.03 (2002) requires that an alternative writ of mandamus shall “state concisely the facts showing the obligation of the defendant to perform the act, and the defendant’s omission to do so.” Generally, mandamus will not issue to compel a public official to do an act absent a request having been made upon the officer to do the act. Alevizos v. Metro. Airports Comm’n of Mpls. & St. Paul, 298 Minn. 471, 496, 216 N.W.2d 651, 666-67 (1974). We have identified two exceptions to this general rule. No request is necessary when a public duty, rather than a private duty, is involved.7 Id., 216 N.W.2d at 667.

We have defined a "public duty" to be one that is specifically stated in the law itself and *492that does not result in a benefit or burden upon any particular person so that no particular person has the right to demand performance. State ex rel. Currie v. Weld, 39 Minn. 426, 428, 40 N.W. 561, 562 (1888).
