Lidl's campaign comparing basket prices across 39 items contained methodological errors including outdated pricing data and unequal product comparisons, according to the ruling. The TV spot reproduced Continente's visual identity and used deprecatory language implying consumers wouldn't return, exceeding legitimate price comparison boundaries.

falhas metodológicas (methodological flaws) - presented as established fact rather than disputed claim
tendenciosa (biased/tendentious) - loaded characterization of product selection

Consumer Goods
Consumers lose access to comparative price information that could inform shopping decisions. The ruling may reduce price transparency in retail advertising, potentially limiting consumer ability to identify cost savings across supermarket chains.
Strengthens advertising self-regulatory enforcement standards for comparative claims in retail. Sets precedent requiring: (1) contemporaneous pricing data within reasonable timeframes, (2) non-biased product basket selection, and (3) transparent competitor identification. May prompt stricter guidelines for promotional campaigns across the sector.
