Whether recharging cadastral surveying costs by a cantonal office is a sovereign activity exempt from VAT or a taxable entrepreneurial activity.
The recharge is taxable; the fact that the office invoices by administrative decision does not turn an otherwise entrepreneurial surveying service into a sovereign activity.
Under both old and new VAT law, surveying-office activities are expressly listed as taxable. Sovereign character depends on the nature of the activity, not on the form of invoicing. Allowing dispositive invoicing to control would let taxable activities escape VAT at will.
