OECD: Conference of the Parties of the MLI approve opinion for MLI interpretation and implementation
On 20 May 2021, the Organisation for Economic Co-operation and Development (OECD) published an Opinion of the Conference of the Parties of the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (MLI) (the Opinion), as approved by the Parties to the MLI under written procedure on 3 May 2021. The opinion sets out six principles for interpretation and implementation of the MLI, which are drawn from public international law, the design of the MLI itself, and its drafting history.
The MLI was developed by an ad hoc group of approximately 100 jurisdictions participating in the OECD Base Erosion and Profit Shifting (BEPS) project. It was agreed in November 2016,1 and it has been open for signature by any interested jurisdictions since then.
To date, 95 jurisdictions have signed the MLI, and 65 jurisdictions have deposited their instruments of ratification, acceptance or approval of the MLI with the OECD. The MLI entered into effect for the first time on 1 January 2019.
According to the text of the MLI, the Parties to the MLI may convene a Conference of the Parties for the purposes of making any decisions or exercising any functions as may be required or appropriate under the provisions of the MLI. Any question arising as to the interpretation or implementation of the MLI may be addressed by a Conference of the Parties. The Conference of the Parties may also be convened to consider amendments proposed by Parties to the MLI.
In March 2021, the OECD announced that the Conference of the Parties to the MLI adopted its first opinion regarding the entry into effect of the MLI with respect to taxes withheld at source in specific cases.2
Opinion of the Conference of the Parties of the MLI
On 20 May 2021, the OECD published the second Opinion of the Conference of the Parties of the MLI to set out principles for interpretation and implementation of the MLI.
According to the Opinion, questions about the interpretation and implementation of the MLI may arise in the following cases: (i) provisions of a Covered Tax Agreement (CTA) modified by the MLI; or (ii) provisions of the MLI itself. For the first category, questions should be settled by mutual agreement in accordance with the provisions of the CTA. For the second category, questions may be addressed by the Conference of the Parties convened in accordance with the procedure set out in the MLI. Further, the MLI should be interpreted in light of the provisions of the Vienna Convention on the Law of Treaties that provides that a treaty (e.g., MLI) shall be interpreted in good faith in accordance with the ordinary meaning to be given to the terms of the treaty in their context and in the light of its object and purpose.
The opinion provides some general treaty interpretation principles, which were approved by the Parties of the MLI on 3 May 2021, and address the following:
Guiding principle 1
The MLI should be interpreted in light of its object and purpose, which is to implement the tax treaty-related BEPS measures.
Guiding principle 2
Each of the provisions of the MLI should be interpreted and implemented in light of the policy objectives of the relevant tax treaty-related BEPS measure. With the exception of Part VI (arbitration) of the MLI, all the substantive provisions in the MLI are intended to be identical in their effect to the provisions that were produced in the BEPS project. Thus, the Commentary developed during the course of the BEPS project and reflected in the OECD Model Convention 2017 has particular relevance. Further, the explanatory statement of the MLI forms part of the context of the MLI and should be taken into account when interpreting the provisions of the MLI.
Guiding principle 3
The MLI does not function in the same way as an amending protocol to a tax treaty, which directly amends the text of the tax treaty. Instead, the MLI applies alongside existing tax treaties, modifying their application in order to implement the tax treaty-related BEPS measures. Some jurisdictions consider that they may need to come to a mutual understanding with the competent authorities of their treaty partners of the precise effects of the modifications made by the MLI on their CTAs. The approach taken by the MLI follows the legal principle that when two rules apply to the same subject matter, the rule that is later in time rule prevails (lex posterior derogat legi priori). If there is a conflict between a CTA and the MLI, i.e., they are incompatible, the MLI prevails over the provisions of the CTA.
Guiding principle 4
The MLI does not modify a CTA beyond the boundaries set out by either of its two Contracting Jurisdictions, as set out in their MLI Positions. This ensures the sovereign autonomy of the Contracting Jurisdictions and the bilateral nature of tax treaties.
Guiding principle 5
When an MLI provision conflicts with an existing provision in a CTA covering the same subject matter, this conflict is addressed through a compatibility clause, which describes the existing provisions that the MLI is intended to modify, as well as the effect the MLI has on those existing provisions. Part VI (Arbitration) of the MLI differs from other provisions and rules for compatibility clauses are consolidated at the end of Part VI of the MLI.
Guiding principle 6
The notification clauses ensure clarity and transparency regarding the existing provisions of CTAs that are modified by the MLI. Notifications made under the MLI may trigger the application of the MLI. However, the extent to which the MLI applies to an existing provision in a CTA is provided in the compatibility clauses.
With its second opinion, the Conference of the Parties seeks to contribute to a consistent interpretation of the impact of the MLI and to a common understanding of the effects of the MLI on the tax treaties it covers and modifies. Taxpayers may find the Opinion of the Conference of the Parties useful and therefore are advised to evaluate each case in light of the traditional sources of interpretation and also putting into context the purpose and objectives of the MLI, i.e., implementation of tax treaty-related BEPS measures.
