The BOURC undertakes:
To maintain the scientific accuracy and integrity of the British List by admitting only those species and subspecies that have been identified beyond reasonable doubt, and whose origin is considered to be in accordance with the relevant BOURC categories.
To ensure that all the evidence for identification and the circumstances surrounding the occurrence of potential new species or subspecies is examined thoroughly, fairly and objectively, calling upon external expert opinion where appropriate.
To ensure that any new evidence which is submitted, or which comes to light, that might affect the identification or categorisation of any existing record is reviewed thoroughly, fairly and objectively.
To ensure that all records are dealt with as speedily as practicable, but not so that this in any way prejudices the need for thorough and comprehensive examination of the evidence.
To attempt to answer any questions about its decisions fully and fairly, stating the reasons for these decisions.
So far as is practicable, to consult with the observers where new evidence suggests that a record might no longer be acceptable. The views of the observers will be taken into consideration in any final decision
