Technical glitches on the Chamber of Deputies' petitions website this week failed to register some signatures and display others publicly, though officials confirm no data was compromised.

The Chamber of Deputies is addressing two technical issues discovered this week on its petitions website, with one problem now resolved and the other nearing a solution.

The first issue exclusively concerned the Luxembourgish version of the site, where online signatures made without electronic authentication (such as Luxtrust or eIDAS) were not registered. This potentially affects 80 petitions.

Of these, the 24 petitions that are still active will have all missing signatures counted retroactively. For petitions that have already closed, the petitioners will be contacted and offered the opportunity to reopen their petition for a new signing period. The Chamber's website notes that since the problem was limited to a specific signing method, it is "unlikely to have had a significant impact on the vast majority of already closed petitions reaching the required threshold for a public debate". Nevertheless, all affected closed petitions will be reopened as a precaution.

A second, separate problem involved the public display of signatures. Some individuals who signed petitions using Luxtrust and opted for a public display did not see their names appear on the site. The Chamber clarified that these signatures were correctly counted but remained invisible. It emphasised that "no identity was revealed against the will of the signatory" and that data protection was maintained, confirming there was no data leak or external hacking.

Chamber Secretary General Laurent Scheeck attributed the incidents to a "strictly technical problem that was not detected when the site was redesigned in March". In a statement to RTL on Thursday, he confirmed there was no external intervention and described the incident as "regrettable", particularly that it was not discovered sooner. Scheeck stated that responsibility lies exclusively with the administration and not with any political officials.
