Ellison, supra, does not stand for the proposition that the mere allegation of the denial of a constitutional right will render a petition for writ of error coram nobis "meritorious" and entitle the petitioner to an evidentiary hearing. The mere allegation that the petitioner was denied counsel, or effective counsel, is insufficient. Ex parte Richards, 42 Ala. App. 461, 168 So.2d 29 (1964). In order for a petition for writ of error coram nobis to be "meritorious on its face" it must contain more than mere naked allegations that a constitutional right has been violated.
