Questão jurídica principal
Whether the housing surcharge and effort rate must be adjusted from the first day of the month following the actual birth date or only from the month after late notification.
Decisão extraída
The decisive date is the date of the change itself, not the date on which it is announced; the surcharge had to be lifted from the first day of the month following the birth.
Fundamentação extraída
A child’s birth changes the family composition and requires a reassessment of the effort rate. Article 11(3) RLGL ties the legal effect to the modification, not to the delay in reporting it; using the announcement date would amount to an unjustified penalty.
