Can the excavated material be used for backfilling?

British Columbia, Canada

The following excerpt is from Carlson v. Hayward dba Hayward Contracting, 2021 BCCRT 317 (CanLII):

19. I find that the question of whether the excavated material could have been used for backfilling is a matter outside of the knowledge of an ordinary person, and must be answered with reference to expert evidence (Bergen v. Guliker, 2015 BCCA 283).
