We eventually end up with constraints of the shape “$\tau_\text{con} \leq \tau_\text{dis}$” and there always exists a $\tau_i \in \tau_\text{con}$ and $\tau'_j \in \tau_\text{dis}$ such that we can reduce the constraint to an equivalent constraint $\tau_i \leq \tau'_j$.” (Parreaux and Chau, 2022, p. 10)
