Plaintiff-appellant Johnny Mitchell appeals from the entry of judgment on a jury verdict in favor of defendants-appellees Randall Drake and the City of Michigan City, Indiana, in an action to recover damages for false imprisonment. In perfecting this appeal appellant seeks to draw into question, through several allegations of error, whether an arrest under the disorderly conduct statute purportedly held unconstitutional, engenders mistаke or illegal process sufficient as a matter of law to require liability for false imprisonment. Appellant ascribes as specific errors: 1) the ruling of the trial court on his motion for partial summary judgment as to the issue of liаbility; 2) its ruling on the exclusion of the record on the previous criminal prosecution against him; and, 3) its giving of an instruction encompassing the disorderly conduct statute. IC 1971, 35-27-2-1 (Burns Code Ed.). Mitchell also argues that the evidence adduced at trial fails to support the verdict. Such verdict is therefore urged as contrary to law.
The record discloses that Officer Drake, while supporting another unit, responded to a complaint concerning a loud and boisterоus teenage street gathering. As he drove next to the curb where several of the youths were dispersing, Johnny Mitchell and a friend began yelling. Officer Drake exited his *378 car to stop Mitchell for an identification of his age. Upon contending with Mitchell’s obscenities and general uncooperativeness Officer Drake placed him under arrest for disorderly conduct. The prosecution of Mitchell was dismissed in the trial court upon a finding that IC 1971, 35-27-2-1, supra, was unconstitutional. 1
Mitchell subsequently brоught this action for false imprisonment against Officer Drake and the City. At the close of the pleadings the trial court denied plaintiff’s motion for partial summary judgment on the issue of liability. Thereafter the trial court refused to admit into еvidence a complete record of the criminal prosecution against Mitchell.
Appellant claims these two rulings as error on the theory that the unconstitutionality of the disorderly conduct statute was a bar which wоuld preclude a defense by Officer Drake and the City on Mitchell’s tort claim.
He further argues that as a matter of law, Officer Drake acted without legal authority, incurring a liability for himself and the City because the prior dismissal of charges against Mitchell for disorderly conduct rested upon a finding that IC 1971, 35-27-2-1, supra, was unconstitutional.
Appellant attempts to draw support for this assertion from
Coleman
v.
Mitnick, etc.
(1964),
*379
However, the unconstitutionality of a statute- is not.-determinative in an action for false imprisonment where, as here, the facts disclose that the arrest and incarceration ocсurred prior to the asserted determination of invalidity. While in theory an unconstitutional law is void
ab initio
and considered as though it had never been passed, properly enacted statutes are presumed valid until a court of cоmpetent jurisdiction has held otherwise.
Ballard
v.
Board of Trustees of Police Pension Fund
(1975),
In
Martin
v.
Ben Davis Conservancy Dist.
(1958),
“The theory that a law held unconstitutional is no law at all аnd void ab initio for all purposes, including retroactive invalidity, runs counter to the hard facts of life. The actual existence of a statute prior to a determination of invalidity is an operative fact. Because of such de facto existence and reliance upon its validity, it has practical consequences which cannot be justly ignored. The past cannot always be erased by a simple judicial decree.”
This court followed the foregoing rationale in
Saloom
v.
Holder
(1973), Ind. App.,
“While it is not unreasonable to presume that a police officer knows the law iii effect at any given time in his jurisdiction, it is folly to presume he can prognosticate unconstitutionality. Courts and commentaries join in proclaiming the absurdity of requiring a law enforcement official to act at his peril in enforcing a statutе or ordinance which is subsequently declared unconstitutional.”
*380
It is clear that since this court presumes the constitutionality of legislative Acts, it will not therefore hold police officers in limbo concerning the enforcemеnt of criminal statutes pending constitutional blessing. Rather they are protected against liability for an arrest pursuant to a statute which is subsequently declared void.

Holder, supra; Stine
v.
Shuttle, et al.

For similar reasons appellant’s contention that the trial court should have admitted the comрlete record of the prosecution for disorderly conduct must also fail. In arguing for the inclusion of the record Mitchell’s apparent purpose was to bring before the jury his motion to quash and his attendant argument on the statute’s unconstitutionality. Appellant relies on general authority recommending inclusion of a prior record of acquittal in cases where it is relevant.
However, while the record of a prior acquittal is required in an аction for malicious prosecution, it is not required where the action has been narrowed to one for false imprisonment based upon an unconstitutional statute.

v.
Lower and Others
(1871),
Moreover the circumstances herein disclosе that certain portions of the record were immaterial to a determination of tortious conduct and therefore had no probative value with respect to the issue of mistake or illegal process.
See generally, Blasche et al.

Himelick, et al. Admrs.
(1965),
Appellant next urges that the trial court committed reversible error by. instructing the jury that there was at the time of the arrest a statute proscribing disorderly conduct. Thе instruction is said to have erroneously rendered verbatim IC 1971, 35-27-2-1, supra, as being dispositive even though it is alleged to have been held unconstitutional by the Michigan City Court during Mitchell’s criminal prosecution.
This assignment of error incorrectly relies оn the assumption that IC 1971, 35-27-2-1,
supra,
was unconstitutional at the time of the arrest and that Officer Drake acted with no authority or color of authority. However, Officer Drake did act pursuant to a statute valid at the time of the arrest and the instruction of the trial court properly so informed the jury.
See, Pierson
v.
Ray
(1967),
Appellant’s remaining argument asserts that the evidence was insufficient to support the verdict and therefore contrary to law in that it failed to show conduct by Mitchell which would justify his arrest. Appellant relies on
Hess
v.
Indiana
(1973),
However the test of probable cause in a criminal proceeding involves a consideration which is not appropriate to a test to be applied in an action for damages. Thus while Officer Drake and the City properly presented evidence to overcome Mitchell’s prima facie case of false imprisonment, they were not required to prove probable
*382
cause to make an arrest in the constitutional framework of a criminal proceeding.
Brubaker
v.
King
(7th Cir., 1974),
“ ‘[T]o prevail the police officer need not allege and prove probable cause in the constitutional sense. The standard governing police conduct is composed of two elements, the first is subjective and the second is objective. Thus the officer must allege and prove not only that he believed, in good faith, that his conduct was lawful, but also that his belief was reasonable.’ Bivens v. Six Unknown Named Agеnts of the Federal Bureau of Narcotics, 2 Cir.,456 F.2d 1339 , 1348 (1972).
As Circuit Judge Lumbard emphasized in his concurrence in Bivens, the reasonable man standard to be applied in tort actions against governmental agents is less stringent than the definition of probable cause applied in criminal prоceedings. Judge Lumbard wrote:
‘This second and lesser standard is appropriate because, in many cases, federal officers cannot be expected to predict what federal judges frequently have considerable difficulty in deciding and about which they frequently differ themselves. It would be contrary to the public interest if federal officers were held to a probable cause standard as in many cases they would fail to act for feаr of guessing wrong.’ Bivens, supra,456 F.2d at 1349 (Lumbard, J., concurring). We conclude, therefore, that it is a defense to an action for damages under § 1983 or the Fourth Amendment for a law enforcement officer to prove that he acted in good faith with a reasonable belief in the constitutionality of his conduct.”
Furthermore the record reveals that in the case at bar a potentially dangerous situation existed. A large group of teenagers had gathered late at night in the Edwards Street neighborhood. Local residents, complaining of the noise, prompted police to patrol the area. After a report that there was a station wagon containing occupants with a rifle nеarby, *383 the officers attempted to disperse the crowd and quell the disturbance.
However Mitchell screamed that they were interfering. Moreover he accosted the officers with obscenities and caused the crowd to regroup. In addition several of the youths began throwing rocks. Thus when Officer Drake tried to ascertain Mitchell’s problem and met only a further harangue, he placed him under arrest.
It is clear that there was ample еvidence to support a finding by the jury that Officer Drake acted in a reasonable manner and was therefore not liable in damages for thé arrest of Mitchell.
For the foregoing reasons the judgment of the trial court must be affirmеd.
Affirmed.
