Can we draw the following hypothesis from the context?

Context:

A three-part referendum was held in Switzerland on 4 October 1896. Voters were asked whether they approved of a federal law on guarantees in the cattle trade, a federal law on the accounting system for the railways and a federal law on the disciplinary penal code for the federal army. Whilst the law on the railways was approved, the other two were rejected by voters.

Hypothesis: Swiss voters went to polls on Saturday
