Key legal question
Whether the cantonal court violated the right to be heard by refusing to take the applicants' 1 September 2010 submission into the record as late.
Extracted holding
Yes. The submission was filed within a time span that was not excessively long after receipt of the opposing parties' observations, so excluding it was incompatible with the right to be heard.
Extracted reasoning
A party served with a response for information only must react without delay if it wishes to reply. Here, the 13-day interval was not excessive, and the appellate court's bare statement that the submission would not change the outcome did not show why it was irrelevant.
