Abstract
The Multilateral Convention to Implement Tax Treaty Measures to Prevent Base Erosion and Profit Shifting or Multilateral Instrument (MLI) has been described as “an historical turning point in the area of international taxation” which introduces a third layer of tax rules for the taxation of cross-border transactions in addition to domestic tax law and bilateral tax treaties. Of the many provisions of the MLI, the most important are the preamble text in Article 6(1) and the so-called principal purpose test (PPT) in Article 7(1), both of which have been adopted by all signatories to the MLI in order to satisfy the OECD’s minimum standard on tax treaty abuse under BEPS Action 6. This two-part article considers the structure and potential application of the PPT in the context of pre-BEPS responses to perceived tax treaty abuses, the OECD’s work on BEPS Action 6, and other provisions of the MLI including the preamble text in Article 6(1). The first part, in the previous issue of the Journal, reviewed pre-BEPS responses to perceived tax treaty abuses, providing necessary background and context for understanding BEPS Action 6, the MLI and the PPT. The second part, in this issue of the Journal, examines the PPT in light of this background and in the context of BEPS Action 6 and other provisions of the MLI, considering its relationship to other anti-avoidance doctrines, principles and rules, the various elements that comprise its basic structure, the kinds of transactions or arrangements to which it may be expected to apply, and the consequences of its application.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
