What persuades
In Servis v. Halaka, Mennen found that a physical therapist's retirement was a significant change in circumstances and ordered his alimony obligation to end after an eight-month step-down.
“Judge Mennen then determined defendant's retirement was a ‘significant change in circumstances’ warranting a modification, ultimately terminating ‘in accordance with the step-down approach.’”
In B9 Schoolhouse Owner v. Township of Franklin, Mennen found that a stormwater ordinance applying to development applicants was a zoning rule subject to the time-of-application statute, rather than a general health-and-safety measure.
“It reasoned the ordinance was ‘far more than a generic environmental regulation’ and not ‘appl[icable] to everyone but instead only those who make an application for development.’”
Procedural preferences
In Servis v. Halaka, Mennen denied a plenary hearing on alimony modification because the opposing certifications raised no genuine factual dispute. The appellate court affirmed his discovery ruling as well.
“The judge reasoned that the conflicting certifications of the parties were ‘conclusory,’ ‘not factual,’ and ‘largely contested [d]efendant's conclusions of law.’”
In Servis v. Halaka, Mennen ordered a two-step reduction before terminating alimony; the appellate court affirmed that approach.
“Based on the record, the judge appropriately ordered a two-step modification of alimony before plaintiff's alimony was terminated.”
Signed rulings
A grounded sample of orders signed by this judge, with the verbatim dispositive language.
“Following oral argument, Judge Mennen rendered an oral opinion and issued a supplemental statement of reasons on September 30, 2022, granting defendant's motion to terminate plaintiff's alimony. In finding that defendant established a ‘good faith retirement,’ the judge ordered the termination of defendant's alimony obligation with an eight-month step-down: effective November 1, 2022, plaintiff's alimony was reduced to $1,500; effective February 23, 2023, plaintiff's alimony was reduced to $750 per month; and effective June 1, 2023, plaintiff's alimony was terminated.”
“In considering plaintiff's cross-motion, Judge Mennen concluded there were no genuine issues of material facts to be resolved by a plenary hearing. The judge reasoned that the conflicting certifications of the parties were ‘conclusory,’ ‘not factual,’ and ‘largely contested [d]efendant's conclusions of law.’”
“plaintiff Kathleen Servis f/k/a Kathleen Halaka appeals a September 30, 2022 order terminating her alimony and denying counsel fees.”
“Defendant Gamal Halaka cross-appeals from the same order, arguing the trial court erred in not terminating alimony effective as of his retirement date of September 30, 2022 and denying counsel fees.”
“In these consolidated actions in lieu of prerogative writs, defendant Township of Franklin appeals a December 6, 2024 Law Division order granting summary judgment in favor of plaintiffs, B9 Schoolhouse Owner, LLC and Concore Realty, LLC”
“After arguments, the court entered summary judgment for plaintiffs and rendered its oral decision on December 6, 2024.”
