The term "undefined" is slightly ambiguous here. If you are asking for a translation of the heading into an unspecified language, I am unable to provide that without knowing which language you are referring to. However, if you meant you want this heading translated into English, here it is: "Swiss Voters Say Yes to the 13th Pension

In a remarkable decision, Swiss citizens voted with a clear majority in favor of introducing an additional, 13th annual pension. The recent referendum, which took place on Sunday, showed that 58 percent of eligible voters supported the proposal of the unions. This result came about despite opposition from the government and parliament, which spoke against the additional pension payment. The peculiarity of the Swiss system requires that a proposal must receive the consent not only of the majority of the overall population but also of the majority of cantons. This hurdle was also cleared, according to the first projections, as Lukas Golder from the polling institute gfs.bern pointed out on Swiss television. In contrast to this decision, the voters rejected another pension proposal, which suggested raising the retirement age beyond 65 years, by a substantial margin. About 75 percent of the voters rejected this idea. Apart from pension policy issues, the population of Zurich voted in a local referendum in favor of an extension of the airport infrastructure. More than 60 percent of those casting votes supported the extension of two runways at Zurich Airport in the projections.
