The slash is inherently ambiguous because it can express either conjunction or disjunction

Evidence

The slash (also called the diagonal, virgule, or solidus) has few uses in formal writing except with dates and fractions. It is best known as the star character in two grammatical abominations: and/or and he/she. It is especially unfit for legal writing because it is inherently ambiguous: its function may be conjunctive <secretary/treasurer> or disjunctive <a buy/sell decision>. — Bryan A.
