Key legal question
Whether the cost of an ice hockey season ticket could be deducted as business expenses for a self-employed dentist.
Extracted holding
No. The season ticket was private expenditure, not economically required for earning income from the dental practice and not deductible as business expense.
Extracted reasoning
The purchase was not caused by the self-employed activity and had no sufficient link to the practice's income generation. It was at most expenditure for social standing or professional appearance, which remains private expense under the tax rules.
