Every organization beyond an individual has a legal system. Whether the rules are formal or informal, defacto or defined is irrelevant, there is a legal system of some sort.

Within the family, it may not be there in writing, but Mom and Dad run the show. The rules are the ones they set for the household. The neighborhood has its norms, unspoken or baked into ordinances. The congregation has its rules, the corner store has a boss that says what goes...

If you have an organization, and it has even the slightest hint of formal governance, you have rules (laws) and a legal system. In this case, yes, chess organizations must deal appropriately with problems of sexual misconduct, including following the laws of the land. In the situations cited in the article, in particular, even if there were now criminal charges leveled, the legal system of the chess federations should have ensured that one member could not gain a position to continue preying on other members. They should do this regardless of what other supervening laws exist. Those other laws will come into play, but there does need to be governance of acceptable behavior within their sphere of concern.
