#### Charles SMITH, Appellant, v. STATE of Florida, Appellee.

No. 77-772.

District Court of Appeal of Florida, Second District.

Dec. 21, 1977.

*206Jack 0. Johnson, Public Defender, Bar-tow, and Douglas A. Wallace, Asst. Public Defender, Bradenton, for appellant.

Robert L. Shevin, Atty. Gen., Tallahassee, and William I. Munsey, Jr., Asst. Atty. Gen., Tampa, for appellee.

SCHEB, Judge.

Appellant/defendant contends the trial court erred in excluding the testimony of a defense witness whose name was not included on the witness lists exchanged pursuant to Fla.R.Crim.P. 3.220 without first making an adequate inquiry into all the surrounding circumstances.

The defendant was tried by a jury on a charge of aggravated assault. At trial the defense called Mrs. Jeannette Smith as a witness. Her name had not been included on the witness list provided to the state pursuant to Fla.R.Crim.P. 3.220.1 The pros*207ecutor pointed out the failure of the defense to disclose this witness to the state, and defense counsel candidly admitted that he had inadvertently failed to include Mrs. Smith on the witness list. The state objected to allowing this witness to testify. The defense made no proffer of the witness’ testimony, and without further inquiry into the circumstances surrounding the failure to comply with the rule the court sustained the state’s objection.

Fla.R.Crim.P. 3.220 provides that the trial court has the discretion to exclude witnesses not included on the witness lists.2 However, the Supreme Court of Florida has held that this discretion may be exercised only after the court has made an adequate inquiry into all of the surrounding circumstances, and failure of the trial court to inquire into these circumstances constitutes error. *Bradford v. State,*278 So.2d 624 (Fla.1973); *Richardson v. State,*246 So.2d 771 (Fla.1971). The inquiry should at least cover whether the violation was inadvertent or willful, whether it was trivial or substantial, the extent of prejudice to the state, and the feasibility of rectifying any prejudice by some means short of excluding the witness. *Bradford, supra; Williams v. State,*264 So..2d 106 (Fla. 4th DCA 1972).

The importance of the omitted witnesses should also, we feel, be taken into consideration.

We therefore hold that the trial court abused its discretion in excluding Mrs. Smith’s testimony without first inquiring into all the surrounding circumstances. The failure of the trial judge to make such inquiry, however, does not require vacation of the judgment and sentence at this time. *Barnes v. State,*294 So.2d 679 (Fla. 2d DCA 1974).

Accordingly, we temporarily relinquish jurisdiction of the cause to the trial court for a period of 45 days from the date of issuance of our mandate. The trial court shall hold a hearing inquiring into the circumstances surrounding defense counsel’s failure to comply with Fla.R.Crim.P. 3.220. The court shall enter an order stating its findings and ruling on whether the state’s objection at trial was well taken. Thereafter, within the said 45-day period, the court shall transmit to this court a transcript of the hearing, and a certified copy of its findings and ruling on the state’s objection. We will thereafter give further consideration to the question raised by this appeal.

GRIMES, Acting C. J., and DANAHY, J., concur.
