This has been achieved through the enactment of a set of legal texts, most notably Law No. 04-02 concerning the rules applicable to commercial practices. This law enshrines the principle of transparency by obliging the economic agent to inform the consumer of all relevant data and information regarding the goods and services involved in the transaction, considering such information a key element in the consumer’s contractual decision. It also obliges the agent to issue an invoice or an equivalent document, especially when requested by the consumer, in order to document the contractual relationship and safeguard the rights of both parties. To ensure compliance with these obligations, the legislator has stipulated a range of sanctions resulting from the violation of the law’s provisions, whether judicial or administrative. This is within an integrated legal framework aimed at achieving a balance in the relationship between the consumer and the economic agent, and protecting both from violations and abuses.otherconsumereconomic agentinvoiceobligationssanctionsThesis
