It is proposed if an auditor of a Town Council can control, without express authorization and through the bills of telephone which it has, to that one who calls to himself, and/or attempt to find out the motive of the call. The exercise of the function of control and taxation of the municipal auditors does not run out exclusively on controlling the amount of the bills, but it could reach all those operations and necessary performances to give fulfillment to the auditor functions, of financial control and of control of efficiency. The knowledge on the part of the auditor of the personal information in question, although not in a generalized way, yes it can be adjusted to the principles of the LOPD in concrete cases. The knowledge on the part of a court qualifier -what the auditor takes part in-, the information could request, as such, that it works out necessary for the fulfillment of its functions. In any case, the Town Council has to keep vigil so that its workers and charges treat the particulars suitably.
