Is it permissible to exclude from a shortlist any job applicants who submit untidy or badly written applications?

Although it is permissible to exclude applicants on the basis of the presentation of their application form or CV, presentation is often irrelevant except in the case of a professional job or one in which the skills of written communication are expressly required for effective performance. If the job is a manual one that does not require any written communication skills, rejection on the grounds of a poorly presented application form would be inappropriate. Furthermore, if the job applicant has a disability, for example dyslexia or learning difficulties, judging them on ability to present the written word could be discriminatory and unlawful.
