OPINION OF THE COURT
This appeal requires us to decide whether plaintiffs sustained the burden of proving diversity of citizenship of the parties in order to confer federal jurisdiction. Specific to our inquiry is a review of the district court’s finding that because defendant intended to remain at his Pennsylvania residence indefinitely, he must be considered a citizen of that state,
After the jurisdictional allegation was traversed, the district court considered evidence produced both by depositions, Tanzymore v. Bethlehem Steel Corp.,
The factual complex presented to the district court was unusual, but the controlling legal principles are well settled. Historical or chronological data which underline a court’s determination of diversity jurisdiction are factual in nature, McSparran v. Weist,
Where the ultimate conclusion is a determination of a party’s citizenship, the requisite intention to establish domicile, and therefore citizenship, is a factual finding. Gallagher v. Philadelphia Transp. Co.,
Therefore, having averred that Brendan Dinan was a “citizen and domiciliary of the State of Connecticut and/or New York,” plaintiffs were obliged to support the allegation of proof once the defendant filed an answer alleging that Dinan was a “citizen and domiciliary of the Commonwealth of Pennsylvania.”
Against the backdrop of these principles, we turn to the evidence adduced by deposition and testimony before the district court. Crucial to these proceedings was the determination of citizenship of Dinan on March 27, 1971, the date the complaint was filed. Dinan described himself as a religious brother, a member of a Roman Catholic semi-monastic teaching order. He took religious vows in 1961 including one to go wherever the Superior General of his Order wished to send him. At various times he was transferred to Indiana, Texas, and New York. In January, 1962, he was transferred to Connecticut where he remained until he went to Bethelem, Pennsylvania, in August, 1968, to take up teaching duties at Bethlehem Catholic High School. Consistent with vows, Dinan owned no property other than clothing contained in a foot locker which accompanied him to Pennsylvania.
When he went to Connecticut, he possessed a Rhode Island driver’s license, which he retained and renewed. In addition, he obtained and renewed one from Connecticut, even while residing in Pennsylvania. At no time did he apply for a Pennsylvania license. On application for renewal of his Connecticut license on December 12, 1968, he listed Bethlehem, Pennsylvania, as his residence. While residing in Pennsylvania, Dinan voted in Connecticut elections by absentee ballot.
When asked for his “official residence” at his first deposition, he responded: “We use New Haven, Connecticut, which is the provincial administration or central office. . . . That is where I vote. It is our central headquarters, because we are moving around somewhat frequently, and you never know how long.”
When a second deposition was taken, Dinan was no longer a resident of Pennsylvania, but was teaching in Brooklyn, New York. He stated that at the time he was stationed there he intended to make Brooklyn his home. When asked why, he replied: “Well, it was my home. I worked there. This is our thinking and you are part of the community, the congregation is. When you go to an area — when you are assigned to an area, this is your home and you become a native.” He testified also that when he was in Connecticut he intended to make that state his home for the same reason. Asked how long he intended to make it his home, he responded: “Forever, I mean, as long as you have no order. I can’t say that I would be there a month or fifty years. This is my home.”
Finally, he was asked about Pennsylvania :
“Q. At the time you were assigned to Bethlehem Catholic High School was there any stipulated term? Were you told how long you would be there ?
“A. No.
*1302 “Q. And where did you intend to make your home upon assignment to Pennsylvania ?
“A. Bethlehem.
“Q. Now at the time you were assigned to and living in Pennsylvania did you have any intention of leaving Pennsylvania at any time and going back to live with your mother ?
“A. Absolutely not.”
On balance, it becomes apparent that the factors bearing on the issue of Din-an’s domicile most favorable to plaintiffs’ theory were: (1) Dinan’s statement at the first deposition that his “official residence” was Connecticut; (2) his continuing to vote in Connecticut by absentee ballot while living in Pennsylvania and (3) his continuing to use a Connecticut driver’s license and a failure to apply for one in Pennsylvania.
Plaintiffs vigorously present the argument that Dinan has but one domicile, in a state outside of Pennsylvania, probably in Connecticut, the self-styled “official residence” of the religious order, and that any teaching assignment elsewhere was similar to a compelled physical presence elsewhere, much the same as the transfer of soldiers whose movements are the result of military orders and not free choice. He would have us invoke the military servicemen principle enunciated in Turek v. Lane,
Dinan attributed his failure to obtain a Pennsylvania driver’s license to financial reasons and to his unwillingness to obtain the medical certificate required in that state. Although the place where one votes has an important consideration, many trial courts have found domicile, and therefore an intention to remain indefinitely, in a place other than where the party voted. Thus, in Ferrara v. Ibach,
“In reviewing the decision of the District Court, our responsibility is not to substitute findings we could have made had we been the fact-finding tribunal ; our sole function is to review the record to determine whether the findings of the District Court were clearly erroneous, i. e., whether we are ‘left with a definite and firm conviction that a mistake has been committed.’ ” Speyer, Inc. v. Humble Oil and Refining Co.,
Applying these principles to the evidence before the fact-finder, we cannot construe, as clearly erroneous, its finding that the defendant “intended to remain in the Commonwealth for an indefinite period of time.” Because animo manendi is at best a subjective manifestation, Dinan’s own declarations of intent are important, as were his explanations of the lack of compulsion in religious order assignments and his failure to obtain a Pennsylvania driver’s license. On balance, plaintiffs were left with the significant factor of Dinan’s continuing to vote in Connecticut. Although this is an important indication of intention, it is not necessary controlling, and was merely one of several indicia properly considered by the court. 2
The judgment of the district court will be affirmed.
Notes
. The commentators appear to have some difficulty as to whether the concept of domicile for federal diversity purposes should be equated with conflict of laws definitions or be recognized as a
sui generis
principle. Compare Hart and Wechsler: “From the beginning the Court has steadily insisted that state citizenship for the purposes of diversity jurisdiction, is dependent upon two elements: first, United States citizenship; and second, domicile in the state, in the traditional sense of the conflict of laws. See
e. g.,
Brown v. Keene,
. Regretfully, one additional comment must be forthcoming. Appellant has assigned as additional ground for reversal the contention that “the Court’s conduct was hostile throughout the hearing, and that he was guilty of abuse and unjudicial action in his remarks concerning plaintiffs’ counsel,” and that “every semblance of Due Process was denied in this hearing.”
At one time the court told counsel: “You can dissent until you drop dead.
I’m sick and tired of hearing it. Go ahead.”
This colloquy between the court and plaintiffs’ counsel, and other colloquies containing remarks of a personal nature from the court to counsel, apparently stemmed from disputes over procedure: whether the requested evidentiary hearing was de novo or designed merely to supplement matters adduced by deposition. Additionally, there was a question whether jurisdiction remained in the district court or whether the proceedings were already in this court on appeal.
Although we have carefully considered appellants’ argument and conclude that no reversible error was committed, this is not to indicate that we approve any injudicious remarks of the trial judge. Trial tactics of energetic counsel may, at times, make it extremely difficult for a court to maintain a calm and dispassionate demeanor. But we find nothing in the record of this case which reveals any deviation by counsel from the proper parameters of advocacy and absolutely nothing warranting the personal comments addressed to him by the trial judge. Although a judge must not be exposed to “undignified and discourteous conduct” .by trial counsel, DR 7-106 (c)(6), Disciplinary Rules, American Bar Association, the court must always be “patient, dignified and courteous toward litigants, jurors, witnesses, lawyers, and others who appear before him. . . .” Proposed Canon 2, Canons of Judicial Ethics, ABA special committee on Standards of Judicial Conduct.
