Opinion by
Judge MacPhail,In these consolidated appeals, the sole issue presented is where venue lies in trespass actions instituted against the Department of Transportation (DOT). In each case, preliminary objections were filed and an appropriate order entered by the trial court. Because the various orders involved controlling questions of law upon which there was substantial ground for difference of opinion, we elected to hear the appeals certified to us pursuant to the provisions of Section 702 of the Judicial Code (Code), as amended, 42 Pa. C. S. §702.
Article I, Section 11 of the Constitution of Pennsylvania provides in pertinent part:
Suits may be brought against the Commonwealth in such manner, in such courts and in such cases as the Legislature may by law direct.
*110Pursuant to that constitutional authority, the legislature has provided as follows:
(a) Venue.-—Actions for claims against a Commonwealth party may be brought in and only in a county in which the principal or local office of the Commonwealth party is located or in which the cause of action arose or where a transaction or occurrence took place out of which the cause of action arose. If venue is obtained in the Twelfth Judicial District (Dauphin County) solely because the principal office of the Commonwealth party is located within it, any judge of the Court of Common Pleas of Dauphin County shall have the power to transfer the action to any appropriate county where venue would otherwise lie.
(b) Process.—-Service of process in -the case of an action against the Commonwealth shall be made at the principal or local office of the Commonwealth agency that is being sued and at the office of the Attorney General.
Section 8523 of the Code, 42 Pa. C. S. §8523.
In Section 3(b) of the Act of September 28, 1978, P.L. 788 (Act), 42 Pa. C. S. App.: 11, it is stated that:
The Attorney General shall promulgate rules and regulations not inconsistent with this act ' in order to implement the intent of the act. The -subject of the rules and regulations may include . . . the designation of local and principal offices for Commonwealth agencies. . . .
Pursuant to that authority, the Attorney General promulgated the following regulations: (1) 37 Pa. Code §111.1, effective January 5, 1980, provided that service of process upon Commonwealth agencies should be made at the principal office or at one of the designated local offices of the agency being sued as *111set forth in a separate sub-section. For DOT, the offices so designated were the Office of Chief Counsel in Harrisburg, Pittsburgh and Philadelphia; (2) 37 Pa. Code §111.2, effective December 26, 1981, provided that venue in actions in trespass against the Commonwealth or Commonwealth parties would lie only in the cause of action county, the county where a transaction or occurrence took place out of which a cause of action arose or where an office of the Commonwealth party had been designated in 37 Pa. Code §111.1. The instant regulation also amended Section 111.1, insofar as designated offices for the service of process on DOT was concerned, to specify that the sole location where process could be served was the Office of Chief Counsel in Harrisburg; and. (3) Effective January 30, 1982, 37 Pa. Code §111.2 was deleted and the Offices of Chief Counsel in Philadelphia and Pittsburgh were added to the designated offices where service of process could be had upon DOT.
Since all of the litigants agree, as they must, that venue in cases where DOT is sued will lie in the cause of action county or a county where a transaction or occurrence took place out of which the cause of action arose, our inquiry here is limited to an interpretation of the meaning of the words “county in which the principal or local office of the Commonwealth party is located.” Section 8523(a) of the Code.
DOT, as we understand its argument, contends that since the Attorney General has deleted 37 Pa. Code §111.2 relating to venue, “local office” must be interpreted as the DOT office responsible for supervising the highway maintenance in the county where the accident occurred or the District Engineering Office for the county in which the accident occurred. In any event, DOT vehemently denies that “local office” can be interpreted as the county highway maintenance *112facility located in each of the 67 counties of the Commonwealth.
Plaintiffs (appellees here), on the other hand, contend in the alternative that either the Attorney General’s designation of the. local offices for the service of process controls, notwithstanding the deletion of 37 Pa. Code §111.2, or that a county highway maintenance facility is a local office in each of the counties of the Commonwealth for the purposes of venue.1
In Cortese v. Department of Transportation, 76 Pa. Commonwealth Ct. 462, 463 A.2d 1293 (1983), we had occasion to construe the Attorney General’s regulations as they existed on January 20, 1982.2 There we held that in view of the Attorney General’s designation of the Office of Chief Counsel in Harrisburg as the “local office” of DOT, a trespass action could be brought against DOT only in Dauphin County or in Wyoming County, the cause of action county. Language in that opinion which is pertinent to the caséis now before us held that “[t]o permit suits against DOT in all 67 counties of the Commonwealth regardless of where the cause of action arose, in our opinion, would be a gross distortion of the intent of the Code.” 76 Pa. Commonwealth Ct. at 466, 463 A.2d at 1295. We affirm that the intent of the Legislature when it used the term “local office” in Section 8523(a) of the Code, was not to open all 67 counties of the Commonwealth to suits against DOT, irrespective of where the cause of action arose. Had the legislature so intended, it easily could have said so by simply providing that suit could be brought in any county of the *113Commonwealth. The statutory language that actions shall be brought in and only in certain counties disavows any legislative intent that suit may be brought anywhere in the Commmonwealth.
We come then to the somewhat difficult question of trying to determine what effect, if any, the deletion of 37 Pa. Code §111.2 has upon the issue now before us. As we have previously noted, the development of the law from the Constitution to the statutory law and then to appropriate regulations, has been an orderly process up to January 30, 1982. We now hold that the deletion of Section 111.2 effective on that date has no effect upon the determination of where venue lies in the cases now before us.
To repeat: (1) Section 8523 of the Code merely says that venue lies in a county where the principal office or local office of the Commonwealth party is located but does not define what a “local office” is; (2) Section 3 of the Act states that the Attorney General shall promulgate regulations to implement the intent of the Act and may designate the local and principal offices for Commonwealth agencies; and (3) the Attorney General has designated the principal offices and the local offices for the various Commonwealth agencies in 37 Pa. Code §111.1. It is true that the designation of such principal and local office in Section 111.1 is for the service of process but nowhere else is there a designation of such principal and local offices, presumably because no one except the Attorney General is authorized to make such a designation. Furthermore, it seems quite logical to us that venue and the place for service of process should be the same, except where suit is brought in the cause of action county. It would seem quite awkward and contrary to our normal procedures to have venue in a county which is not the cause of action county and *114service of process in yet another county.3 Our legislature does not intend a result that is absurd, impossible of execution or unreasonable. Section 1922(1) of the Statutory Construction Act of 1972, 1 Pa. C. S. §1922(1).
DOT’s own designation of counties where venue will lie is not authorized by statute nor is it the subject of any regulation adopted by it. Persons desiring to sue DOT would have no way of determining what alternatives they have to the cause of action county unless they first ascertain from DOT the appropriate county having supervisory responsibility for highway maintenance in the county where the accident occurred or the location of the District Engineering Office. This, we believe to be cumbersome, unnecessary and unauthorized by law.
We hold that trespass actions against DOT may be brought in the cause of action county, the county where a transaction or occurrence took place out of which the cause of action arose or the county wherein is located the principal or local office of DOT as designated by the Attorney General in 37 Pa. Code §111.1 (b).
We now proceed to apply our decision to the cases pending before us.

Judge Williams, Jr., did not participate in the decision in this case.An amicus brief from the Pennsylvania Trial Lawyers Association urges us to adopt either of these alternatives.
It may be noted that all of the accidents in the cases now before us occurred after January 30, 1982, the effective date of the 37 Pa. Code §111.2 deletion.
Compare Pa. R.C.P. No. 1006(a) which provides that venue in actions at law against individuals may be brought in and only in a county where process may he served or where the cause of action arose, or where a transaction or occurrence took place out of which the cause of action arose or in any other county authorized by law.
Chatzidakis argues to us that DOT’S appeal here has been untimely filed. A motion to quash DOT’S appeal for that reason was previously filed and heard by Judge Cbaig who denied the motion. That ruling is the law of the case on that issue and will not be considered in this opinion.
