Corporate campaign donations

In the ADI 4650 case, the STF banned contributions from public and private legal entities to either candidates or political parties. The court ruled that such types of political donations violated the Constitution – despite the existence of no constitutional clause on the matter. The decision marks a new phase for the Brazilian political funding system, which had been based on exclusively public financing in the 1970s and on mixed financing in the 1990s. I gather the main criticisms against the ruling into 2 categories: de facto and legal claims. I do so in order to demonstrate that: firstly, by abruptly restricting the contribution to parties and campaigns without an equivalent reduction in spending, the STF forced political agents to pursue new sources of public and private financing, with disastrous consequences for the political financing system; and secondly, it remains highly debatable whether the court’s decision was in fact based on any constitutional principle.
