1.Periods of leave and the period following the drawing up of a probationary report are to be taken into account in calculating the period of the probationary period referred to in Article 34(1 ) of the Staff Regulations, since that provision does not require that the duties should be actually carried out during the whole of the probationary period ( see the judgment of 15 May 1985 in Case 3/84 Patrinos v Economic and Social Committee (( 1985 )) ECR 1421 ).
In consequence, in the case of a probationary official prevented from working because of illness, the appointing authority, which has a discretion, but no obligation, to extend the probationary period, may consider the probationary official' s performance of his duties during a shorter period in order to assess his abilities if that period constitutes a sufficient basis of assessment for the reporting officer .
2.It is apparent from the second paragraph of Article 34(2 ) of the Staff Regulations that where a probationary official' s abilities are the subject of an adverse interim report, of which there need be no prior warning to him, the appointing authority has a discretion to continue the probationary period or to dismiss the probationary official in accordance with the procedure provided for therein .
3.It is not for the Court to intervene in the assessment made by the institutions of the outcome of a probationary period or in their appreciation of the suitability of a candidate for a permanent appointment in the Community civil service, except where there are manifest errors of assessment or there is a misuse of powers ( see the abovementioned judgment of 15 May 1985 ).
