The short answer
There are two types of block in the law. The first is mandatory: the platform must block anyone who does not meet the legal requirements, such as an expired certificate or an uninsured car (article 14(2)). The second is contractual: since 2026, access and blocking clauses must be included in the adhesion contracts between the platform and operators, be made public and be notified in advance to the AMT, which can order them to be corrected (article 20(8) and (9), and article 5(3) to (5)). The law does not provide for prior notice, a right of reply or an internal appeal for the driver. What you can do depends on which of the two blocks is involved.
First step: work out what kind of block this is
Article 14(2) already existed in 2018: the platform manager "must block access to its services for TVDE operators, drivers or vehicles that fail to meet any of the requirements referred to in this law, whenever it knows or ought to know of this". With the newIMT data platform, the app will check those requirements against an official source (article 20(5) to (7)).
The most common legal grounds for a mandatory block can therefore be checked:
- TVDE or taxi driver certificate expired or seized;
- driving licence no longer valid;
- vehicle not registered with the IMT, without an up-to-date inspection, without valid TVDE insurance or over the age limit;
- operator without a valid licence;
- limit of ten hours of driving in 24 hours reached, which the platform must enforce (article 13(1) and (2)).
In this case there is nothing to challenge with the platform: the solution is to sort out the requirement. If the requirement is met and the block is due to a data error, the law penalises the platform manager that communicates "inaccurate, incomplete or outdated" data to the IMT platform (article 25(2)(aa)).
Access and blocking clauses: the big change
In 2018, the law only regulated adhesion contracts with passengers, making them subject to the rules on standard contract terms (article 5(2)). The relationship between the platform and operators was left out of the text. The 2026 revision changes this in article 20(8): the platform manager "defines and makes public the adhesion contracts for TVDE operators to its platform, which must include, in particular, the clauses on access and blocking of operators, drivers and vehicles on the TVDE electronic platform, notified in advance to the AMT, their effectiveness depending on acceptance by the TVDE operator".
Four rules follow from this sentence:
- operators’ adhesion contracts must exist and be made public, meaning they can be consulted;
- they must include the access and blocking rules, including for drivers and vehicles;
- those clauses must be notified to the AMT before they are used;
- they only take effect if the operator accepts them.
AMT scrutiny: 20 days and standard contract terms
Article 20(9) applies to these contracts, "with the necessary adaptations", paragraphs 3 to 5 of article 5, which are also new in 2026. The mechanism is as follows:
- the platform manager sends the AMT the templates and all subsequent changes (paragraph 3);
- the AMT may, within 20 days, notify the platform manager to correct clauses it considers not to comply with the law; if it does not, this counts as a favourable opinion (paragraph 4);
- a favourable opinion does not close the door: the AMT retains the "power of supervision at any time" over the legality of the clauses (paragraph 4);
- if the platform manager keeps clauses that received an unfavourable opinion, the AMT must act under articles 25 and following of Decree-Law no. 446/85, the law on standard contract terms (paragraph 5).
The law does not say from when the 20 days are counted or whether they are working days. There are two associated fines, both attributable to the platform manager and processed by the AMT: failing to send the templates (article 25(2)(d), which expressly refers to article 20(9)) and using clauses that received an unfavourable opinion (paragraph (e)). For legal persons, they range from 5,000 to 44,000 euros.
The duty to inform the driver
The driver does not sign the adhesion contract, but the law does not leave them in the dark. Article 20(10) requires the platform manager to inform the driver, "when they register on the platform, of the adhesion contracts signed by their respective TVDE operators". This is new in 2026. In practice, it means the blocking rules that may be applied to you should be shown to you before you start.
