The Law's measure is regularity, not frequency. Art. 2(c) of Law No. 5187 defines a periodical as printed works "published at particular intervals"; it sets no lower limit on how long the interval may be.

Where Is the Distinction?

Subpara.ConceptDefinition
cPeriodicalPrinted works such as newspapers and magazines published at particular intervals, together with the publications of news agencies and internet news sites
hNon-periodicalPrinted works such as books and gift volumes not published at particular intervals

The Interval Is Declared

Art. 7 requires the information "the intervals of publication" to be shown on the declaration. For an annual publication that information is declared as "once a year".

The Real Risk: The One-Year Period in Art. 9

For a publication appearing once a year the distance between the declaration and the first issue is naturally long. If the declaration is filed early and the first issue exceeds one year, the declaration lapses.

The Three-Year Interruption Period

The second period is easier for annual publications: the declaration lapses if publication is interrupted for three years after it has begun. For a publication appearing once a year that means not appearing for three years in a row.

The Position on the Press Card Side

The Obligations Are the Same

To the extent it counts as a periodical, all the obligations apply:

  • Declaration - to the public prosecutor's office for the place of management (Art. 7)
  • Responsible editor - every periodical has one (Art. 5)
  • Imprint - the place of management, owner, representative, responsible editor and publication type (Art. 4)
  • Delivery - the printer delivers two signed copies to the prosecutor's office on the day of distribution (Art. 10)
  • Reply and correction - in non-daily periodicals, in the first issue after three days from the date the text was received (Art. 14)

Summary

  • A publication appearing once a year is a periodical so long as its interval is particular, and is subject to the periodical obligations.
  • The real risk is the one-year period in Art. 9: if the first issue does not appear within a year of the declaration, the declaration becomes void.
  • Confirm its position in the press card regime separately.
