OPINION
PER CURIAM:


1
Joseph Bernard Droback appeals an order adjudging him in contempt of court for refusing to testify before a federal grand jury after the court granted him immunity under 18 U.S.C. §§ 6002--6003, and ordered him to testify.  We affirm.


2
The only issue is whether a grand-jury witness whose identity and possible knowledge of crime have been discovered through a court-ordered wiretap may, by refusing to testify, delay the proceedings while he conducts a plenary challenge of the electronic surveillance.  He may not.  In re Persico, 491 F.2d 1156 (2d Cir.), cert. denied, 419 U.S. 924, 95 S.Ct. 199, 42 L.Ed.2d 158 (1974).


3
Droback contends that In re Lochiatto, 497 F.2d 803 (1st Cir. 1974), compels a contrary result.  We disagree.  But even if Lochiatto conflicts in part with Persico, we believe that Persico more accurately reflects congressional policy authorizing a narrow range of court-ordered wiretaps than does Lochiatto.


4
Droback's interpretation of the cases would require the grand-jury investigation of any witness to come to a halt any time the witness chooses to assert some latent defect in the court order or its underlying papers, or some defect in the conduct of the surveillance.


5
We decline to hold that an immunized witness can stop the investigation, assert his list of objections, proceed with comprehensive discovery, and ultimately have a full-fledged suppression hearing to determine whether or not the court order allowing the surveillance or the manner of its execution is vulnerable to some attack.


6
The immune witness is, in effect, seeking to convert his contempt proceeding into a bystander's action to test the legality of a surveillance program which is likely to produce evidence against one or more of his associates.  We doubt that Congress intended to permit such delays, and, in the absence of Supreme Court direction to do so, we will not reach that result.


7
Affirmed.
