The UCI has stated that it is still evaluating the situation, however a look at the UCI's own regulations doesn’t clarify the situation. According to Article 2.15.009, “A maximum of 18 UCI WorldTour team licences may be issued....”, and the UCI now faces a WorldTour with 19 teams.
The rules seem to require that the WorldTour licences awarded this year be re-awarded. “Every licence shall be granted subject to a possible redistribution of the licences following a decision of the CAS cancelling a refusal to grant a licence pursuant to Article 2.15.241,” according to Article 2.15.026 of the UCI's regulations.
That later article directly addresses what is to happen if a Licensing Committee decision is annulled. In that situation, “the case shall be returned to the licence commission. After consulting the parties, the commission may, if it considers that it is in possession of adequate information, renounce any further documentary submissions and/or hearings. The case shall then be adjudged on the basis of the licence application documentation as submitted to the commission on the occasion of its initial decision.”
That leaves the situation unclear as to what decision the Commission is able to take. In this particular instance, the CAS has said that Katusha must be given the WorldTour licence.
Well, can the UCI now do a redistribution in which Katusha is eliminated (despite what CAS ruled)? UCI could claim that Katusha got the license, but did not hold on to it in the redistribution.
