Thirteen organizations ask Congress to validate the Lobbying Law and process the text later as a bill.

The so-called “Royal Decree-Law on lobbies” is the Royal Decree-Law 21/2026, of August 25, on transparency and integrity of interest group activities, published in the BOE on August 26, 2026 and in force since then (text in the BOE). As of today, September 15, 2026, its parliamentary processing is at the stage of validation or repeal in the Congress, and it has still not been formally decided whether it will be processed as a bill.

1. Identification and regulatory context

• Regulation: Royal Decree-Law 21/2026, of August 25, on transparency and integrity of interest group activities (state register of “lobbies”, definition of interest groups, influence activity, publicity obligations, sanctioning regime, etc.). The BOE itself refers to this title and framework (BOE).
• Proposing Ministry: Ministry for Digital Transformation and Public Function.
• Blocked precedent: the Bill on transparency and integrity of interest group activities, with file number 121/000046, is still formally under processing in the Congress (process process_ini_360183), with:
  • Registration in Congress on 01/30/2025 and admission for processing on 02/07/2025.
  • Deadline for amendments to the articles on 09/10/2025.
  • Rejection of Vox's total amendment and approval of referral to the Plenary for the final vote (09/17/2025) (BOCG series A 46-4).
  Despite this, both the European Commission's note and specialized press indicate that by mid-2026 the bill had not yet been approved by the Congress nor sent to the Senate, so the Government opted for the decree-law due to this blockage (see, for example, Demócrata, “Brussels suspends Spain for keeping lobby regulation blocked” and “The Government creates by decree the mandatory public lobby register due to the blockage in Congress”).

2. Parliamentary situation of Royal Decree-Law 21/2026

Regarding the Royal Decree-Law 21/2026 itself, official data and parliamentary agendas show that:

• The decree-law was approved by the Council of Ministers on August 25, 2026 and published in the BOE on August 26 (BOE; also referenced in the Moncloa note on the Council of Ministers agreement, accessible from the same process).
• According to article 86 of the Constitution, it must be submitted to validation or repeal by the Congress within a maximum period of 30 days.
• The Agenda of the Congress Plenary for today, September 15, 2026, includes under point VI the “Validation or repeal of Royal Decree-Laws”, with the Royal Decree-Law 21/2026 as initiative no. 130/000052:
  • “Royal Decree-Law 21/2026, of August 25, on transparency and integrity of interest group activities. (BOE no. 209, August 26, 2026). (File no. 130/000052)” (Agenda of the Plenary, Congress of Deputies, session of 09/15/2026, available on the Congress website).
• That is, early on 09/15/2026 the regulation is pending that validation or repeal vote; no result has been recorded yet.

3. Conversion into a bill and expected deadlines

In the case of a decree-law, the Congress Rules allow that, once validated, the Plenary may agree to process it as a bill, usually by the urgency procedure. Several journalistic analyses explicitly recall this for this case (for example, Demócrata, “Lobby law: the five mistakes that leave it on the verge of falling in Congress”).

However, with the information available today:

• There is no formal agreement yet from the Congress Plenary deciding to process Royal Decree-Law 21/2026 as a bill. Such agreement, if adopted, would occur in the same plenary session in which its validation is voted on.
• Consequently, there is no closed parliamentary calendar yet (dates for committee, commission, possible sending to Senate) for its processing as a bill. That calendar would be set later by the Congress Board and the Spokespersons' Board, once:
  • a) the decree-law has been validated, and
  • b) the Plenary has expressly agreed its conversion into a bill.
• In any case, the ordinary route would be: validation in Congress Plenary → agreement to process as a bill (likely by urgency) → sending to competent Committee (Finance and Public Function) for report and opinion → new Congress Plenary → referral to Senate → return to Congress if applicable.

4. Practical conclusion as of today (09/15/2026)

In summary:

• The Royal Decree-Law 21/2026 (“on lobbies”) is in force since its publication in the BOE on 08/26/2026.
• Its parliamentary processing is at the validation/repeal stage in Congress, with debate and vote scheduled for today's Plenary, 09/15/2026 (file no. 130/000052).
• It has not yet been decided whether its processing will continue as a bill; that decision depends on what the Plenary agrees today after the validation vote. Therefore, there are no official deadlines set yet for its debate as a bill either in Congress or in the Senate.
• The previous lobby bill (file no. 121/000046) remains formally alive in Congress, but its processing was blocked and has been practically displaced by the new decree-law.

The royal decree-law is an exceptional legislative instrument of the Government, reserved for cases of extraordinary and urgent necessity, which comes into force immediately after its publication in the BOE. Precisely because of this entry into force prior to parliamentary debate, the Constitution and the legal system assign the Congress of Deputies a central control role on two levels: the validation or repeal of the decree-law within a very short period, and the possible processing of it as a bill to submit it to the ordinary legislative procedure.

1. Control of validation or repeal within 30 days

The first competence of the Congress is the immediate political and legal control of the royal decree-law. Once approved by the Government and published in the BOE, the Congress must decide within a maximum period of 30 days whether to validate or repeal it. This provision aims to balance governmental urgency with parliamentary centrality in normative production.

The debate and vote on validation take place in the Plenary of the Congress. In that debate:

• The Government defends the royal decree-law and justifies the existence of the extraordinary and urgent necessity, as well as the content of the measures adopted.
• The different parliamentary groups state their position, evaluating both the form (use of the decree-law, urgency, affected matters) and the substance of the regulation.
• A vote is held in which the Congress decides whether the royal decree-law is validated —that is, remains in force— or repealed.

The result of that vote has very clear effects:

• Validation: the Congress ratifies the royal decree-law, which continues in force as a norm with the rank of law, without the need for a new approval. The extraordinary control linked to urgency is considered overcome.
• Repeal: if the Congress decides not to validate it, the royal decree-law ceases to have effect. From that moment it is no longer in force, without prejudice to the legislator deciding to regulate the matter again by other normative means.

2. Decision on processing as a bill

In addition to validation or repeal, the Congress may decide that the royal decree-law be processed as a bill. This second decision is autonomous from validation: even if validated, the Congress may consider it appropriate to submit the text to a full legislative procedure that allows amendments.

When the Congress agrees to that processing, the royal decree-law becomes a bill, and follows the general rules provided for these:

• Opening of a period for submission of amendments by parliamentary groups, both to the whole and to the articles.
• Possible referral to committee for the preparation of a report, with internal debates and votes where amendments are incorporated, modified, or rejected.
• Debate and vote in Plenary of the report and reserved amendments, in terms analogous to any ordinary or urgent bill.
• Subsequent referral to the Senate, where amendments can also be presented and debated, thus completing the bicameral circuit typical of ordinary legislation.

In this scenario, the text born as a royal decree-law is subjected to much more intense parliamentary scrutiny and open to modifications, allowing adjustment of the initial regulation, correction of technical defects, modulation of its scope, or introduction of additional guarantees.

3. Material functions of the Congress in this scheme

Overall, the powers of the Congress of Deputies regarding royal decree-laws can be grouped into three main functions:

• Political and constitutional control function: by assessing whether the conditions of extraordinary and urgent necessity exist and whether the affected matters respect limitations (for example, not affecting areas reserved for organic law or the general electoral regime), the Congress acts as guarantor of the correct use of this exceptional instrument.
• Legislative function of ratification or rejection: through the vote of validation or repeal, the Congress decides whether to assume the norm approved urgently by the Government as its own or, on the contrary, to annul it, returning the situation to the previous framework or opening the door to other legislative solutions.
• Normative improvement function: when it opts for processing as a bill, the Congress turns a text approved in an accelerated manner into the starting point of a complete legislative process, with participation of all groups, amendments, and bicameral reading in Congress and Senate. In this way, it integrates governmental urgency into the ordinary normative production channel.

In short, although the royal decree-law is born within the Government and comes into force without prior intervention of the Cortes, the Congress of Deputies retains final control over its validity, effectiveness, and possible transformation into law, ensuring that the instrument's exceptionality does not empty the principle of parliamentary centrality in the legislative function.

In the Spanish parliamentary system, a royal decree-law (RDL) can be “converted” into a bill when, at the time of its validation, the Congress of Deputies agrees to process its content as a bill. It is not a new independent initiative, but rather submitting the text of the RDL itself to the ordinary legislative procedure, generally by the urgency procedure.

1. Basic constitutional and regulatory framework

The key elements are:

• Spanish Constitution: recognizes the figure of the decree-law and assigns the Congress the competence to validate or repeal it and, if applicable, to process it as a bill.
• Rules of the Congress of Deputies: develop the procedure for processing bills (publication, amendments, committee, plenary, referral to Senate) and regulate the legislative procedure in general, including urgency.
• Rules of the Senate: regulate the intervention of the Upper House when the text of the already validated RDL reaches the Senate as a bill.

The regulations and parliamentary practice, as reflected in the multiple validation agreements published in the BOE (resolutions of the Congress ordering the publication of validation agreements of royal decree-laws), show that the decision to process an RDL as a bill is adopted in the very Plenary that debates the validation.

2. Prerequisites: approval and referral of the decree-law

Before the option to process the RDL as a bill exists, these steps must be fulfilled:

• Approval by the Government in the Council of Ministers of the royal decree-law, alleging the occurrence of an extraordinary and urgent necessity.
• Publication in the BOE, the moment when the RDL comes into force.
• Immediate referral to Congress for its debate and vote of validation or repeal in Plenary.

Without this validation debate, there can be no talk of conversion into a bill, because it is in that same session when Congress adopts, if applicable, the formal agreement to process it as such.

3. Decision of Congress: validation vote and agreement on processing as a bill

In the Congress Plenary two differentiated decisions occur:

• Vote on validation or repeal of the royal decree-law. If Congress repeals it, the RDL ceases and there is no possibility to process it as a bill in ordinary terms; a new legislative initiative would have to be presented.
• Agreement on its processing as a bill. If the RDL is validated, the Plenary may decide that its content be processed as a bill. This decision:
  • Is adopted through a formal agreement of the Congress Plenary, usually in the same session and after the debate on the RDL.
  • Is processed at the request of the Government itself or parliamentary groups, but the ultimate competence is the Plenary.

From a legal-parliamentary point of view, this agreement is the core requirement for the text of the decree-law to “pass” to the ordinary bill channel: without it, the RDL remains validated and in force as is, but without opening the amendment procedure.

4. Nature and effects of the agreement: start of the legislative procedure

Once the RDL is validated and the agreement to process it as a bill is adopted:

• The text of the royal decree-law is considered, for all procedural purposes, as a bill submitted by the Government, as described in the Rules of the Congress: it is published, an amendment period is opened, and it is sent to the competent committee.
• The legislative procedure for bills applies, but usually under the form of urgency procedure, which implies shortening deadlines in Congress and Senate, to avoid a norm already in force remaining too long without definitive full legislative “coverage.”
• The RDL remains in force while the bill processing lasts; the text finally approved may:
  • Reproduce the content of the decree-law in full, or
  • Modify it totally or partially through amendments approved in Congress and Senate.

5. Subsequent development: amendments, committee, Plenary, and Senate

After the agreement of the Congress Plenary, the bill follows the general course described by the parliamentary Rules themselves:

• Publication and opening of the amendment period by parliamentary groups (to the whole and to the articles).
• Committee and Subcommittee, which prepare and debate a report and opinion on the text and amendments.
• Debate and vote in the Congress Plenary of the report and the amendments still alive, approving a text that is sent to the Senate.
• Action of the Senate, which may approve the text, amend it, or veto it, with the effects and possible new votes in Congress foreseen for any bill.

In summary, the specific legal requirement to “convert” a royal decree-law into a bill is the agreement of the Congress Plenary, adopted after its validation, to process its content as a bill —usually by urgency procedure— from which point the entire ordinary legislative procedure for Government-submitted bills unfolds.
