Six refugees, out of eight people are due to appear in a French court on Monday after boarding on a ferry in Calais, breaking the port barrier.
The refugees, coming from the so-called Jungle camp, participated in a 2,000 people protest on January 23, demanding to enter Britain.
As the protest was coming to an end, 150 people broke through a barrier in the port and managed to board on the "Spirit of Britain" ferry.
The police removed them three hours later while 24 refugees and 11 No Border activists were arrested
The eight people that had to attend court will get a verdict from a court in Boulogne-sur-Mer on Monday.
The Jungle camp has been widely criticised over its living conditions as it is set up on a former toxic waste dump.
The French authorities have decided to shut the camp down and move the refugees elsewhere.
According to local authorities, there are approximately 3,700 people living in the "Jungle" camp in northern France most dream of crossing to Britain.
The port security measures, considered tighter than before, raise questions about port's effectiveness.
The situation in the camp gained even more attention when celebrities like Jude Law and Benedict Cumberbatch called on the British government to open the borders especially for children who already have families in Britain.
Camp to be demolished
In the meantime, authorities had cleared out a section of the camp forcing hundreds of refugees to move.
After clearing this section, the entire southern part of the camp was next, affecting between 1,000 and 2,000 residents.
The demolition of the section could start on Tuesday night.
The judge in the case is due to visit the Jungle on Tuesday before giving a verdict later in the day.
The Calais town hall stated on Friday that the demonisation comes as a result of “abuses” made by refugees which created tension in the camp.
The refugees are expected to be moved elsewhere in the country or to repaired containers put next to the camp.
