Executive Summary: Key Legal and Evidentiary Issues

• Four of the six documents WPNL sought to admit as evidence of damages (Documents A, B, E, and F) were excluded as inadmissible due to non-compliance with pre-trial disclosure rules under the Rules of the Supreme Court, 1986.

• Documents C and D were admitted — the customer list was already in evidence, and the volumes document was substantially a disclosed update of a prior undertaking.

• Admitting undisclosed documents mid-trial would constitute "trial by ambush," causing irreparable prejudice to SPHL that neither an adjournment nor cost awards could cure.

• WPNL's Controller, Vanessa Whiteway, was barred from testifying about the contents of the inadmissible documents, as doing so would allow WPNL to accomplish indirectly what it could not do directly.

• The "litigant-witness with expertise" framework invoked by WPNL did not apply here, as the underlying data she would have relied on was itself inadmissible and undisclosed.

• Disclosure obligations extend to the underlying data — not just the compiled documents — meaning WPNL's claim that documents were "recently created" did not excuse the failure to disclose the information they contained.

A family business, a fuel sale, and a non-compete dispute

Skinner's Plumbing & Heating Ltd. (SPHL) was a small, family-run operation based out of the Skinner family home in Newfoundland, engaged in both furnace repairs and petroleum delivery. Derek Skinner Sr. handled the repair side, while his wife Barbara managed fuel deliveries. By 2018, Barbara had grown frustrated with the challenges of the petroleum delivery business and approached Western Petroleum Newfoundland Limited (WPNL) about selling that portion of the company. The sale was completed on October 1, 2018.

The terms of the transaction

Under the Asset Purchase Agreement (APA), SPHL transferred its delivery trucks, customer records, goodwill, and personal property of the petroleum business to WPNL. In return, WPNL agreed to pay $125,000 in cash, $196,054.29 for accounts receivable, and $1,274,307.84 structured as "future management fees" payable over 48 monthly installments of $23,085.29. Notably, WPNL's CFO acknowledged these payments were deliberately labelled as management fees for tax purposes, allowing WPNL to deduct them as operating expenses rather than capital expenditures — even though the Skinners performed no actual management work.

Alongside the APA, both SPHL and the Skinners personally signed a Non-Competition and Confidentiality Agreement, which prohibited them from competing with WPNL in fuel distribution or sharing customer information with competitors. This agreement explicitly barred SPHL from disclosing customer contact details to rival companies.

The alleged breach and competing claims

Shortly after the deal closed, Derek Skinner Jr. — a full-time SPHL employee but not an owner — and two business partners launched a competing oil delivery company called Reliable Fuels. Once WPNL discovered this, it informed the Skinners, who terminated Derek Jr.'s employment. Over the following months and years, WPNL noticed it was not retaining former SPHL customers at the anticipated rate and suspected that the customers were being poached by Derek Skinner Jr. and his partners at Reliable Fuels. In April 2021, WPNL formally accused the Skinners of violating the Non-Competition Agreement by deliberately passing the customer contact list to Derek Jr. and Reliable Fuels, and immediately stopped paying the outstanding monthly management fee installments. SPHL responded by suing WPNL for breach of contract, while WPNL counterclaimed against both SPHL and the Skinners.

The evidentiary dispute at trial

The case was scheduled for a six-day trial beginning March 31, 2025. A prior court order had required WPNL to deliver any actuarial evidence on damages at least 60 days before the settlement conference — but no actuarial report was ever filed. WPNL instead pivoted to relying on its own employees to prove damages. Only six weeks before trial, WPNL revealed it planned to compare customer retention rates between the SPHL acquisition and a separate acquisition of another fuel company called Bluewater.

On September 10, 2025 — mid-trial — WPNL disclosed six documents it wished to introduce through its Controller, Vanessa Whiteway, to prove the quantum of its damages. These documents included Bluewater customer volume data (Document A), a summary of WPNL's expected profits described as an analysis of Skinner's impact (Document B), a reordered SPHL customer list (Document C), actual SPHL post-acquisition volumes (Document D), and two versions of expected profit projections (Documents E and F). SPHL objected, arguing that these documents had not been properly disclosed and that WPNL was attempting to introduce expert opinion evidence through its own employees without following the required procedural steps.

The court's analysis of disclosure obligations

Justice Mellor applied a two-step framework: first, determining whether each document was properly disclosed under the Rules of the Supreme Court, 1986; and second, whether the court should exercise its discretion to admit improperly disclosed evidence under Rule 46.14. The factors considered included the extent of the rules breach, the reliability and relevance of the documents, prejudice to either party, the interests of justice, and whether a reasonable explanation existed for the non-disclosure.

Documents A, B, E, and F were all found to be prima facie inadmissible. WPNL's List of Documents had been filed as far back as September 10, 2021, and a Certificate of Readiness was signed on March 1, 2024 certifying that document exchange was complete — yet none of the Bluewater-related or profit-margin data appeared in that list. The court rejected WPNL's argument that the documents were only "recently created" in January 2025 and therefore could not have been disclosed earlier, noting that the underlying data had been in WPNL's possession for years. WPNL's own Trial Brief admitted that performance data "were kept contemporaneously as WPNL tracked [SPHL's] performance."

Document E was found particularly troubling due to a massive volume discrepancy — the document reported 474,252.90 litres of furnace oil for the period October 1, 2019 to September 30, 2020, whereas another disclosed document (Tab 27) showed 5,255,096.00 litres for the same period — casting serious doubt on its reliability. The court declined to accept that data drawn from internal systems was inherently reliable.

Documents C and D, however, were admitted. The customer list (Document C) had already been disclosed and was in evidence in another format, and the actual SPHL volumes document (Document D) was an updated version of "Schedule G," which had been properly disclosed as part of WPNL's earlier discovery undertaking.

The witness testimony question and the ruling

WPNL sought to have Vanessa Whiteway testify about her "observations" of the commercial data in the inadmissible documents, arguing she was a "litigant-witness with expertise" whose evidence was admissible regardless of whether the documents themselves were admitted. The court rejected this argument. Justice Mellor noted that no case — civil or criminal — had permitted a witness to testify about calculations performed on data that was itself inadmissible due to non-disclosure. Allowing such testimony would permit WPNL to do indirectly what it could not do directly, and would place SPHL in an even worse litigation position, as it would have to either forgo cross-examination or seek to put into evidence the very documents it had successfully argued to exclude.

In the result, Documents A, B, E, and F were ruled inadmissible, and Vanessa Whiteway was barred from testifying about those documents' contents. The court ordered that costs shall be in the cause, meaning the costs of this evidentiary motion will be decided at the conclusion of the broader trial. The exact amount of any damages award in the underlying breach of contract action cannot be determined from this decision, as this ruling addressed only evidentiary admissibility — not the ultimate merits of either party's claim.
