OPINION AND ORDER
SCHEINDLIN, District Judge.
I. INTRODUCTION
On April 20, 2005, this Court issued an Opinion and Order ("Order"), denying, in large part, defendants' motions to dismiss the complaints filed in fifteen states. Although familiarity with the Order is assumed, it generally held that plaintiffs' claims could go forward based on theories *322 of collective liability.[1] Certain defendants now move for certification to pursue an interlocutory appeal pursuant to section 1292(b) of Title 28 of the United States Code.[2]
II. LEGAL STANDARD
It is a basic tenet of federal law to postpone appellate review until a final judgment has been entered.[3] However, a court may certify an order for interlocutory appeal if each of the following conditions are met: the order "[1] involves a controlling question of law [2] as to which there is substantial ground for difference of opinion and [3][ ] an immediate appeal from the order may materially advance the ultimate termination of the litigation."[4] But even where the criteria of section 1292(b) appear to be met, district courts have "unfettered discretion to deny certification" if other factors counsel against it.[5]
"In determining whether a controlling question of law exists the district court should consider whether: reversal of the district court's opinion could result in dismissal of the action; reversal of the district court's opinion, even though not resulting in dismissal, could significantly affect the conduct of the action; or, the certified issue has precedential value for a large number of cases."[6] "Although the resolution of an issue need not necessarily terminate an action in order to be `controlling,' it is clear that a question of law is `controlling' if reversal of the district court's order would terminate the action."[7]
The second requirement is a "substantial ground for difference of opinion."[8] The mere presence of a disputed issue that is a question of first impression, standing alone, is insufficient to satisfy this prerequisite.[9] The district court must analyze *323 the strength of the arguments in opposition to the challenged ruling,[10] and determine whether there is "substantial doubt" that the district court's order was correct.[11]
Finally, "`[a]n immediate appeal is considered to advance the ultimate termination of the litigation if that appeal promises to advance the time for trial or to shorten the time required for trial.'"[12]
III. DISCUSSION
A. The April 20 Order Did Not Advance A Liberal Construction Standard
Defendants argue that the Order should be certified because this Court erroneously applied a "liberal construction of state law" standard, which "provide[d] Plaintiffs much more than they would receive in a state court, since it resulted in the Court resolving virtually all legal issues in Plaintiffs' favor."[13] This argument is without merit.
The Order applied no such standard of review. Defendants have focused on five words of the Opinion while completely ignoring the remainder. I prefaced my rulings by explaining that it was this Court's duty to predict what the highest court of a particular state would decide if presented with the issue of collective liability.[14] I stated:
When a defendant removes a case from state to federal court, a liberal construction of state law protects the principle of dual sovereignty by protecting a party who sought to obtain a resolution of state law claims from state courts. If this Court were to adopt a more restrictive reading of state law than the highest courts of the relevant states would be likely to adopt, the parties would be treated differently than they would be in a state court. . . .[15]
I further explained that plaintiffs would not be prejudiced by the removal of their cases to federal court, and that they were being afforded "the same treatment [they] would receive in state court  no more, and no less."[16] Thus, all that was meant by the phrase "liberal construction of state law" was that the Court would interpret state law the same way  rather than more restrictively than  the relevant state supreme court would.
B. The Requirements for Certification Have Not Been Met
1. Collective Liability Rulings
Defendants contend that the Order should be certified because the Court's collective liability rulings are at odds with decisions made by other courts that have rejected collective liability theories.[17] While the issues presented to this Court *324 raised questions of first impression in many states, I relied on substantial state case law, state statutes, and the Restatement of Torts in determining that plaintiffs' claims may proceed.[18] The arguments and authorities cited in defendants' briefs were thoroughly considered and found to be inapposite.[19] "[A] party that offers only arguments rejected on the initial motion does not meet the second requirement of § 1292(b)."[20] Therefore, defendants have failed to show that there is substantial doubt regarding the correctness of the Court's collective liability rulings sufficient to justify interlocutory appeal.
Furthermore, defendants have not demonstrated that interlocutory appeal would materially advance the ultimate termination of the litigation. These cases are in the midst of intensive discovery, and plaintiffs continue to seek individualized proof of product identification through product tracing. If plaintiffs discover such evidence, they will, where feasible, pursue the actual tortfeasors, rather than rely on theories of collective liability.[21] Thus, even if the Court's Order were reversed, the litigation would not terminate because plaintiffs would proceed on traditional causation theories. Defendants have thus failed to meet the third requirement for 1292(b) certification.
2. Fraud Rulings
Defendants also argue that this Court should certify the Order for appeal because rulings regarding causes of action sounding in fraud in the Connecticut and Iowa cases present a substantial ground for difference of opinion.[22] However, these rulings do not provide a basis for 1292(b) certification because they do not constitute controlling issues of law, and an appeal would not advance the ultimate termination of the litigation. Plaintiffs assert numerous causes of action against defendants other than the fraud claims. Moreover, the fraud rulings only apply to cases filed in two out of the fifteen states addressed in the Order. Therefore, reversal would not result in the dismissal of the actions, would not significantly affect the conduct of the actions, and would not have precedential value for other cases in this multi-district litigation.[23] In addition, dismissal of the fraud claims would neither advance the time for trial nor shorten the time required for trial.
The requirements of section 1292(b) have not been met. Accordingly, defendants' motion for certification to pursue interlocutory appeal is denied.
IV. CONCLUSION
For the reasons set forth above, defendants' motion for 1292(b) certification is denied. The Clerk of the Court is directed *325 to close this motion. A conference is scheduled for September 9, 2005, at 10:00 a.m.
SO ORDERED.
