«The same obligation is pointed out by José Luís Moreira da Silva, a Partner at SRS Legal, who recalls that this organisation has criticised the state in the past.
He warns that in order to abolish tolls on the ex-Scut "it is not enough for legislation to come into force", since "when there is a contract that provides for a certain economic and financial situation and this is altered by a legislative act, the grantor has to rebalance the contract due to the loss of revenue or increase in costs".
Recalling that contracts have had to be renegotiated in the past, particularly in order to introduce tolls on the Scut, Moreira da Silva talks about the experience of litigation because "the figures that the concessionaires present are not accepted by the state" and it has to be proven that there is "too little revenue or too many costs".
In these cases, he explains, the concessionaire has six months to present the case and the REF request, admitting that the negotiation "may take its time", but makes it clear that "without an agreement it will go to arbitration".»
