OPINION OF THE COURT
Plaintiff’s diversity action appeal from the district court’s direction of a verdict for defendant questions whether the court erred in failing to find a pri-ma facie case of liability and in refusing to consider an alleged violation of the Pennsylvania Health and Safety Act of May 18, 1937, P.L. 654, 43 Pa.Stat.Anno. § 25-1, et seq. The appeal also raises the question of abuse of discretion in pretrial rulings.
Plaintiff, an electrician, alleged that he was injured when he fell three feet from a ladder after being overcome by “noxious fumes” while working in a room under construction for Sylvania Electric. He introduced testimony that the room was hot, was poorly ventilated, and that there were odors from fresh paint and from the installation of floor tiling. Although Sylvania owned the property, it had let the construction work to a prime contractor, an electrical contractor, and a heating contractor. Thus, we do not reach the issue of whether plaintiff’s evidence was sufficient to prove proximate cause because we are convinced that plaintiff failed to prove that Sylvania was sufficiently in control of the premises so as to impose liability for negligence. Fisher v. United States,
Plaintiff argues that his trial counsel was not sufficiently familiar with the case at the time he entered his appearance fifteen months after plaintiff’s prior counsel filed the complaint. It is his contention that although a pretrial hearing had already been conducted, new counsel’s request for additional time for discovery should have been granted. We find no merit to this argument. We note that the court did in fact permit a supplemental pretrial statement to be filed on October 28, 1970, and conducted a supplemental pretrial conference on November 4, 1970. We can find no abuse of discretion here.
At trial plaintiff sought to impose liability on two grounds — a statutory violation suggesting negligence
per se
and common law negligence. Contending that the trial court erred in preventing him from introducing the provisions of the Pennsylvania Health and Safety Act,
supra,
appellant infers that this exclusion constituted prejudicial error “because it forced him to rely on general principles of common law negligence by denying him the benefit of Pennsylvania’s time-honored rule that a violation of a statute may be negligence
per se
upon which liability may be grounded if such negligence is the proximate and efficient cause of the incident. Kaplan v. Philadelphia Transportation Co.,
The Court: [A]nd as I understand it, there is no allegation of violation of ordinances like Department of Labor regulations or any other statutory or quasi-statutory regulations.
*84 Plaintiff’s Counsel: No. Because I anticipated that probably I would get into some difficulty.
Although now asserting that he is not bound by this position because of a change in trial counsel, we believe that the dictates of orderly trial procedure compel him to adhere to those theories he adopted at pretrial. F.R.C.P. 16 states:
The court shall make an order which recites . . . the agreements made by the parties as to any of the matters considered, and which limits the issues for trial to those not disposed of by admissions or agreements of counsel; and such order when entered controls the subsequent course of action, unless modified at the trial to prevent manifest injustice.
Whether to admit evidence supportive of a theory not disclosed during pretrial is a matter peculiarly within the discretion of the trial judge. In Ely v. Reading Co., 424 F.2d 758 (3d Cir. 1970), this court stated:
One of the main purposes of the pretrial conference is to formulate the issues to be litigated to aid the parties in preparation for trial. If counsel are permitted to change the positions taken at pretrial obviously the effectiveness of this procedure is destroyed. For this reason the pretrial order is generally binding on the parties. It cannot be modified without the permission of the court and a showing of manifest injustice. The decision of whether or not to permit a change is within the discretion of the trial judge. Appellate interference with this discretion should be kept at a minimum. It should only be exercised where there is a clear abuse of discretion.
Putting aside this question of estoppel, we find that the court did not err in refusing to consider the substantive provisions of the Pennsylvania Health and Safety Act. In Millard v. Municipal Sewer Authority,
swpra,
If indeed such rules and regulations exist, plaintiff made no offer to introduce them.
We have carefully considered all other contentions presented in this appeal and find them to be devoid of merit. 1
The judgment of the district court will be hffirmed.
Notes
. In any event, we perceive a jurisdictional problem in the complaint. It is proper for this court to inquire into the jurisdictional prerequisites
sua sponte.
