1. The impugned decision is set aside.
2. The complainant is entitled to the full amount of the non-resident allowance without gradual reduction.
3. The Organization shall pay the complainant the sum of 5,000 Swiss francs in costs.
When it comes to interpretation, the primary rule is that words are to be given their obvious and ordinary meaning (see Judgment 1222, under 4) and any ambiguity in a provision should be construed in favour of staff and not of the Organization (see Judgment 1755, under 12).
