The opposition has argued that the bill, adopted by Parliament on December 20, violated the constitutional principle whereby laws may not be applied retroactively and also violated the principle that private property is inviolable.

The opposition said in its claim the bill regulating the display of advertising banners allowed local authorities to remove them through administrative means, regardless of whether the banners were displayed on public or private property, without requiring a removal authorization or a court order.

The Parliament will have to correct the aspects of the bill the Court found unconstitutional.
