Indirect surveys are mandatory for natural persons, legal entities and organisations that carry out public tasks.15.
The survey shall be conducted in a format that imposes the least possible administrative burden on those under obligation.
Any person who provides information voluntarily for a survey must do so in a truthful manner and to the best of their knowledge. The Federal Council may provide compensation for voluntary information where its provision requires an exceptional amount of time and effort from the interviewees.
The Federal Council may on, commissioning a survey, require natural persons and legal entities under private and public law and their representatives to disclose information if this is absolutely necessary for the completeness, representativeness, comparability or up-to-dateness of a statistic. The persons and entities under this obligation are required to provide the information truthfully, within the deadline, free of charge and in the prescribed form.16
