column does not belong to table Table

Question

I don't know exactly where I have to look for. Error is:

Column 'pkJudge' does not belong to table Table. '
   at System.Data.DataRow.GetDataColumn(String columnName)
   at System.Data.DataRow.set_Item(String columnName, Object value)
   at ReadyCollect.CaseEntry.S_GetJudges(Int32 courtID)
   at ReadyCollect.CaseEntry.S_GetExistCaseInfo()
   at ReadyCollect.CaseEntry.CaseReminder_HoldCase()
   at ReadyCollect.CaseEntry.btnSave_Click(Object sender, EventArgs e)

It occurs in the following code fragment. Any Ideas?

Private Sub S_GetJudges(ByVal courtID As Integer)
    ' Load the list of judges   '
    Dim JudgeSet As New DataSet
    Dim dv As System.Data.DataView
    Dim DAl As New DataAccessLayer
    Dim pfkCourt As Integer = CourtDDL.SelectedValue

    If ClientKey > 0 And pfkCourt > 0 Then
        JudgeSet = DAl.GetJudgespkJudgesJudgeNamefkCourt(ClientKey, pfkCourt)
        JudgeDataTable = JudgeSet.Tables(0)
        Dim dr As System.Data.DataRow
        dr = JudgeDataTable.NewRow()
        dr("pkJudge") = "0"
        dr("Judge Name") = "(Select a Judge)"
        JudgeDataTable.Rows.Add(dr)
        JudgeDDL.SelectedValue = 0
        JudgeDDL.DataSource = JudgeDataTable.DefaultView
        dv = JudgeDataTable.DefaultView
        dv.Sort ="pkJudge ASC"
        JudgeDDL.DataBind()
    End If
End Sub

And the dataaccess method that is called in the code fragment is below. Now JudgeDataTable is declared as
Private JudgeDataTable As System.Data.DataTable on top of the page.
Rest is in the code fragment as I posted above.

'Retreives fields pkJudge and [Judge Name] from the table Judges where field fkCourt is equal to fkCourt '

Public Function GetJudgespkJudgesJudgeNamefkCourt(ByVal ClientKey As Integer, ByVal fkCourt As Integer) As DataSet
    Dim db As Database = DatabaseFactory.CreateDatabase()
    Dim sqlCommand As String = "USP_DISPLAYJUDGESPKJUDGEJUDGENAMEFKCOURT"
    Dim dbCommand As DbCommand = db.GetStoredProcCommand(sqlCommand)
    db.AddInParameter(dbCommand,"ClientKey", DbType.Int32, ClientKey)
    db.AddInParameter(dbCommand,"fkCourt", DbType.Int32, fkCourt)
    Return db.ExecuteDataSet(dbCommand)
End Function

What happens if you break after the getdataset stuff and look at the datatable? Is the column there? Otherwise, maybe try to access it via column index.
