On July 25th 1914, the Serbian government responded to the Austro-Hungarian ultimatum, acceding to most – but not all – of Vienna’s demands:
The Royal [Serbian] Government cannot be made responsible for expressions of a private character, as for instance newspaper articles and the peaceable work of societies, expressions which are of very common appearance in other countries, and which ordinarily are not under the control of the state. This, all the less, as the Royal Government has shown great courtesy in the solution of a whole series of questions which have arisen between Serbia and Austria-Hungary, whereby it has succeeded to solve the greater number thereof, in favour of the progress of both countries.
The Royal Government was therefore painfully surprised by the assertions that citizens of Serbia had participated in the preparations of the outrage in Sarajevo. The Government expected to be invited to cooperate in the investigation of the crime, and it was ready, in order to prove its complete correctness, to proceed against all persons in regard to whom it would receive information.
According to the wishes of the [Austrian] Government, the Royal Government is prepared to surrender to the court, without regard to position and rank, every Serbian citizen for whose participation in the crime of Sarajevo it should have received proof. It binds itself particularly on the first page of the official organ of July to publish the following enunciation:
“The Royal Serbian Government condemns every propaganda which should be directed against Austria-Hungary, i.e., the entirety of such activities as aim towards the separation of certain territories from the Austro-Hungarian monarchy, and it regrets sincerely the lamentable consequences of these criminal machinations…”
The Royal Government confesses that it is not clear about the sense and the scope of that demand of the [Austrian] Government which concerns the obligation on the part of the Royal Serbian Government to permit the cooperation of officials of the [Austrian] Government on Serbian territory, but it declares that it is willing to accept every cooperation which does not run counter to international law and criminal law, as well as to the friendly and neighbourly relations.
The Royal Government considers it its duty as a matter of course to begin an investigation against all those persons who have participated in the outrage of June 28th and who are in its territory. As far as the cooperation in this investigation of specially delegated officials of the [Austrian] Government is concerned, this cannot be accepted, as this is a violation of the constitution and of criminal procedure. Yet in some cases the result of the investigation might be communicated to the Austro-Hungarian officials.
