specially concurring.
I concur with the majority's conclusion that prior decisions of this Court require the denial of relief in this case. However, I agree with Justice Overton's dissents in Riley v. State, 433 So.2d 976 (Fla.1988), and Hallman v. State, 371 So.2d 482 (Fla.1979), which reject the conclusiveness test in the review of petitions for writ of error coram nobis.
