At the request of a private client of the Mallorca-based law firm Bennàssar advocats, my services as a computer forensics expert were requested in the context of an administrative litigation claim.

The claimant took part in a competitive examination organised by the Island Council of Mallorca. As part of that competitive examination, certain physical tests had to be passed. The claimant requested, through administrative channels, a review of his score in the examination phase, for which he requested the videos of the physical tests he completed.

After the update of his score was denied at the administrative stage, legal proceedings were initiated through administrative litigation. In the context of those legal proceedings, we formalised an engagement letter for a computer forensics expert report on the originality and non-manipulation of the physical test videos.

The videos recorded a series of repetitions of bench press and pull-ups performed by the claimant. However, the examining board responsible for supervising the competitive examination process deemed a number of repetitions of those physical tests invalid. It should also be noted that the videos were recorded from 3 cameras, positioned from different viewpoints, covering a 180° angle.

With this working scenario, in addition to assessing the originality and non-manipulation of the videos, the expert report provided graphic evidence of the repetitions that were not counted. A comparative study was carried out between the images of the repetitions that were not counted and those that were counted, in order to demonstrate the error in the tally of repetitions not counted by the examining board.
