Re: How Many Welfare Checks Are Permissible
The police are simply responding to a call for service. Whether they must conduct the check or not depends on state law. I doubt there is a state law mandating a check, but it tends to be far easier to check and find that nothing is wrong that it is NOT to check and then learn that a child is injured.
Some agencies here will only conduct these checks when there is some articulated reason to believe the child might be at risk, and just saying that there has been no goodnight phone call is not enough. Further, people have been prosecuted for violating restraining orders through unfounded calls to the police. Unfortunately, many people then learn to make those calls anonymously and then the police still tend to respond.
The bottom line is that you may have little recourse unless the police decide that mom can be charged with a crime of some kind. Or, perhaps you can seek a court order (restraining order, condition of custody, something) that restricts the circumstances under which she can make these calls. If there is still a restraining order in place and prohibits harassment, then you might want to seek enforcement of this through the court ... provided her checks are groundless.
