In Weir v. State, 319 So. 2d 80, 81 (Fla. 2d DCA 1975), the second district specifically held that coram nobis was available in a situation where a defendant wished to challenge a 30-year-old plea-based conviction on grounds that "at the time of the entry of his judgment and sentence he was a youth of twenty years of age, uneducated in the law and without any funds with which to obtain legal assistance in his defense." See Weir, 319 So. 2d at 80-81. In Weir, the court held: "The mere passage of time, standing by itself, would not constitute the prejudice necessary to support a finding of laches." Weir, 319 So. 2d at 81.
