Prawo i Sprawiedliwość (Law and Justice)
Excludes 3 sittings the Parliament officially excused (Rule 162)
View official EP profile →Credited roll-call participation in each calendar month of the current 180-day window of the 10th term, from the same per-sitting counts as the headline figure. Officially excused sittings (Rule 162) are removed from that month's denominator — a gap in the line is a fully excused month. The dashed line is the mean of ranked MEPs' monthly rates. How this is calculated
Every plenary sitting day on which this MEP missed at least one roll-call vote, newest first. “Officially excused” means the Parliament's own record excuses the absence; those sittings are already credited in the figure above. Links open the Parliament's record for that day. How this works

Summary grounded in cited sources
View official profile on europarl.europa.eu →Attendance is calculated based on roll-call votes in plenary sessions of the European Parliament. Committee votes are excluded. Abstaining counts as present; not voting counts as absent. Sittings for which the Parliament officially excused a Member (Rule 162: illness, serious family reasons, official mission, or pregnancy and maternity leave, which the Parliament excuses for three months before and six months after a birth) are credited, not counted as absences. We credit only what the Parliament's own record shows: the “excused” list in each sitting's minutes, or leave documented in another official Parliament document. An absence the Parliament has not recorded as excused counts as an absence, even if leave has been reported in the press. Notable votes are selected based on significance, close outcomes, and high participation.
Some attendance figures carry a context note, such as maternity or parental leave, illness or an official mission. Each note cites a press or official report, with its source and date, and is reviewed by us before it appears. Context notes never change the attendance figure. MEPs who missed every sitting of an entire plenary session are checked by a person before they appear in any bottom-of-ranking list. Full attendance methodology →
