3 An alleyway breached across its full width into a courtyard, and the courtyard is breached on its other side toward a public domain — if the courtyard residents did not make an eruv with the alleyway residents, the courtyard is permitted, even if the breach faces the alleyway's breach and even if many people pass through it, provided it is no more than ten handbreadths. The alleyway is forbidden even if it does not face the courtyard's breach, since not having made an eruv with the alleyway restricts it — this applies when the alleyway walls extend into the courtyard such that the remaining side-sections within the courtyard are not visible to one standing in the alleyway. But if they are visible, they count as a lechi and it is permitted. If the courtyard residents did make an eruv with the alleyway residents, and the breach from the alleyway into the courtyard is not on the courtyard's side, and the courtyard's breach on the other side does not face the alleyway's breach, and the courtyard belongs to many — the alleyway is also permitted. But if they did not make an eruv, or even if they did but the courtyard's breach toward the alleyway is on its side, or even in the middle of the courtyard and the courtyard's breach on the other side faces it, or even does not face it but the courtyard belongs to a single individual — it is forbidden. If the breach opens into an area smaller than two *se'ah*, or larger but enclosed for dwelling purposes, it is treated as a breach into a courtyard. But if it is larger than two *se'ah* and not enclosed for dwelling, it is as if it opened into a *karmelit* and requires rectification.
