Whatever are in the terms and conditions of the lender.
If you've gone over your limit it's because the minimum payment was less than the previous balance plus the interest accrued in the month.
With a 31 day month and interest accruing on/around weekends, it's certainly possible for the interest on a balance to vary quite a bit from month to month.
So, yes it's possible and this is probably what happened, and if it's within their T&Cs it's perfectly legal for them to do this.
Yet another example of why they say you should be careful making minimum payments, as the payment is based on the balance+interest of the previous month, not the currently accruing month.
