We agree in both respects. Potee v. County Comm'rs of Anne Arundel County, 138 Md. 381 (1921). Judge Harris found that McCarty had "failed to sustain his burden of proof."
In an application for mandamus all the facts necessary for the writ must be stated and proved or admitted on the record. Sudler v. Lankford, 82 Md. 142, 148, 33 A. 455; McCurdy v. Jessop, 126 Md. 318, 324, 95 A. 37; Potee v. County Commissioners of Anne Arundel County, 138 Md. 381, 113 A. 884. The writ of mandamus is not granted ex debito justitiae.
