  Reconnecting vortices in a superfluid allow for the energy transfer between
different length scales and its subsequent dissipation. The present picture
assumes that the dynamics of a reconnection is driven mostly by the phase of
the order parameter, and this statement can be justified in the case of
Bose-Einstein Condensates (BECs), where vortices have a simple internal
structure. Therefore, it is natural to postulate that the reconnection dynamics
in the vicinity of the reconnection moment is universal. This expectation has
been confirmed in numerical simulations for BECs and experimentally for the
superfluid ${}^4$He. Not much has been said about this relation in the context
of Fermi superfluids. In this article we aim at bridging this gap, and we
report our findings, which reveal that the reconnection dynamics conforms with
the predicted universal behaviour across the entire BCS-BEC crossover. The
universal scaling also survives for spin-imbalanced systems, where unpaired
fermions induce a complex structure of the colliding vortices.
