Key legal question
Whether a 19% salary decrease constitutes a significant change of income under Art. 11(3) RLGL, and how fluctuating income must be annualized.
Extracted holding
Yes. A 19% salary decrease is a significant modification of income. Where income fluctuates over three months, the authority must annualize the average income earned during those three months, not the income of a single month.
Extracted reasoning
The court held that using one month alone would distort the assessment when earnings are variable. The proper reference point is the average of the actual income received over the relevant three-month period.
