The law is the result of the projects of the Ecological Party “Os Verdes” (PEV) and Bloco de Esquerda (BE) and makes an amendment to the so-called Legal Regime of the General Contractual Clauses, which applies to contracts, from insurance to communications, to gas and electricity, and from water to gyms.

The PS abstained and the CDS voted against the diploma. The, PSD, BE, PCP, PAN, PEV, Chega, Liberal Initiative and the two non-registered deputies Joacine Katar Moreira (ex-Livre) and Cristina Rodrigues (ex-PAN) voted in favour.

In its project, BE claimed that, many times, “the text of the clause” is “excessively complex, to the point of making it difficult to read and understand”, to which is added “use of tiny characters” that “makes reading difficult”.

The PEV argued that "clauses printed in such a small font that it is almost impossible to read" endsup leading the consumer to not understand "what they are signing".

The law also provides for the creation of an "administrative system for the control and prevention of unfair terms".
