To understand the gravity of this ruling, we must consider its origins. The PGMOL case stemmed from years of litigation focused on the principles of mutuality in employment status. The Supreme Court ultimately dismissed HMRC’s arguments that centered around mutuality and payment for work done, clarifying that referees do not have guaranteed appointments — a key indicator of non-employment.

This outcome is significant because it suggests a shift in how employment status is evaluated under the IR35 legislation. The court found that the relationship between referees and PGMOL lacked the defining hallmarks of employment. Taken cumulatively, these factors indicate a lack of mutual obligation, which is critical to determining whether someone is an employee or self-employed.

Key facts about the PGMOL ruling:

• The PGMOL decision clarified the principles of mutuality in employment status cases.
• HMRC’s CEST tool has not been updated since November 2019 despite legal clarifications in April 2022 and September 2024.
• The Supreme Court found no guarantee of appointments for referees, indicating non-employment.

This context matters because it directly influences how other professions might be evaluated under similar circumstances. For instance, if referees are not considered employees due to a lack of mutuality, what does that mean for other gig economy workers? How many others might find themselves categorized as self-employed despite their daily realities suggesting otherwise?
